  • Scattering matrix and analytic torsion
    • Abstract: Publication date: Available online 9 October 2017
      Source:Comptes Rendus Mathematique
      Author(s): Martin Puchol, Yeping Zhang, Jialin Zhu
      We consider a compact manifold with a piece isometric to a (finite-length) cylinder. By making the length of the cylinder tend to infinity, we obtain an asymptotic gluing formula for the zeta determinant of the Hodge Laplacian and an asymptotic expansion of the L 2 torsion of the corresponding Mayer–Vietoris exact sequence. As an application, we give a purely analytic proof of the gluing formula for analytic torsion.

      Author(s): Anis S. Hoayek, Gilles R. Ducharme, Zaher Khraibani
      In a time series { X t , t ≥ 1 } , X j is said to be an upper record if X j > max ⁡ { X 1 , … , X j − 1 } . Some popular models for records are the Yang–Nevzorov and the Linear Drift models. In this note, we introduce for these models the joint likelihood of the record sequence and the indicators of their occurrence. This likelihood can then be used to obtain estimators of the unknown parameters in the models. It can also be used to derive inferential procedures associated with the selection of a proper model for such data.

      Let P ( z ) be a polynomial of degree n and for any complex number α, let D α P ( z ) : = n P ( z ) + ( α − z ) P ′ ( z ) denote the polar derivative of P ( z ) with respect to α. In this paper, we present an integral inequality for the polar derivative of a polynomial. Our theorem includes as special cases several interesting generalisations and refinements of Erdöx–Lax theorem.

      Motivated by a previous work by Zheng and the second-named author, we study pinching constants of compact Kähler manifolds with positive holomorphic sectional curvature. In particular, we prove a gap theorem following the work of Petersen and Tao on Riemannian manifolds with almost-quarter-pinched sectional curvature.

    • Abstract: Publication date: Available online 3 October 2017

      Author(s): Paata Ivanisvili, Fedor Nazarov, Alexander Volberg
      In the present paper, we show that a correctly chosen Legendre transform of the Bellman functions of martingale problems give us the right tool to prove isoperimetric inequalities on Hamming cube independent of the dimension. We illustrate the power of this “dual function approach” by proving certain Poincaré inequalities on Hamming cube and by improving a particular inequality of Beckner on the Hamming cube.

    • Abstract: Publication date: Available online 29 September 2017
      Source:Comptes Rendus Mathematique
      Author(s): Semyon Litvinov
      This article gives an affirmative solution to the problem whether the ergodic Cesáro averages generated by a positive Dunford–Schwartz operator in a noncommutative space L p ( M , τ ) , 1 ≤ p < ∞ , converge almost uniformly (in Egorov's sense). This problem goes back to the original paper of Yeadon [21], published in 1977, where bilaterally almost uniform convergence of these averages was established for p = 1 .

  • On the representation by sums of algebras of continuous functions
    • Abstract: Publication date: Available online 29 September 2017
      Source:Comptes Rendus Mathematique
      Author(s): Aida Kh. Asgarova, Vugar E. Ismailov
      We give a necessary condition for the representation of the space of continuous functions by sums of its k closed subalgebras. A sufficient condition for this representation problem was first obtained by Sternfeld in 1978. In case of two subalgebras ( k = 2 ), our necessary condition turns out to be also sufficient. If k = 1 , our result coincides with a version of the classical Stone–Weierstrass theorem.

  • An improved SSA forecasting result based on a filtered recurrent
           forecasting algorithm
    • Abstract: Publication date: Available online 28 September 2017
      Source:Comptes Rendus Mathematique
      Author(s): Hossein Hassani, Mahdi Kalantari, Masoud Yarmohammadi
      The Singular Spectrum Analysis (SSA) technique is a non-parametric powerful method in the field of time series analysis whose popularity has increased in recent years owing to its widespread applications. Recurrent forecasting is one of the important forecasting methods in SSA. In this paper, the forecasting accuracy of recurrent forecasts is improved via the introduction of a new recurrent forecasting algorithm. In the novel approach, the recurrent coefficients are generated from the filtered series which has less noise and thus enables one to achieve the better forecasts. The performance of the new method has been compared with the established recurrent forecasting method. The comparison involves applications to various real and simulated time series. The obtained results confirm that the new approach can provide more accurate forecasts.

More specifically, we will present several new constructions of convex bodies: the geometric mean of two convex bodies, the power function K α (which in general exists only for α ≤ 1 ), and even the logarithm log ⁡ K .

      Author(s): Augusto C. Ponce, Daniel Spector
      We present the fractional perimeter as a set-function interpolation between the Lebesgue measure and the perimeter in the sense of De Giorgi. Our motivation comes from a new fractional Boxing inequality that relates the fractional perimeter and the Hausdorff content and implies several known inequalities involving the Gagliardo seminorm of the Sobolev spaces W α , 1 of order 0 < α < 1 .

      Author(s): Amod Agashe, Lydia Eldredge
      A theorem of Matsushima–Shimura shows that the space of harmonic differential forms on the quotient of products of upper half planes under the action of certain groups, when the quotient is compact, is the direct sum of two subspaces called the universal and cuspidal subspaces. We generalize this result to compact quotients of products of upper half planes and upper half spaces (hyperbolic three spaces) under the action of certain groups to obtain a similar decomposition.

  • Simplicial complexes and closure systems induced by indistinguishability
           relations
    • Abstract: Publication date: Available online 27 September 2017
      Source:Comptes Rendus Mathematique
      Author(s): Giampiero Chiaselotti, Tommaso Gentile, Federico Infusino
      In this paper, we develop in a more general mathematical context the notion of indistinguishability, which in graph theory has recently been investigated as a symmetry relation with respect to a fixed vertex subset. The starting point of our analysis is to consider a set Ω of functions defined on a universe set U and to define an equivalence relation ≡ A on U for any subset A ⊆ Ω in the following way: u ≡ A u ′ if a ( u ) = a ( u ′ ) for any function a ∈ A . By means of this family of relations, we introduce the indistinguishability relation ≈ on the power set P ( Ω ) as follows: for A , A ′ ∈ P ( Ω ) , we set A ≈ A ′ if the relations ≡ A and ≡ A ′ coincide. We use then the indistinguishability relation ≈ to introduce several set families on Ω that have interesting order, matroidal and combinatorial properties. We call the above set families the indistinguishability structures of the function system ( U , Ω ) . Furthermore, we obtain a closure system and an abstract simplicial complex interacting each other by means of three hypergraphs having relevance in both theoretical computer science and graph theory. The first part of this paper is devoted to investigate the basic mathematical properties of the indistinguishability structures for arbitrary function systems. The second part deals with some specific cases of study derived from simple undirected graphs and the usual Euclidean real line.

  • Plus and minus logarithms and Amice transform
    • Abstract: Publication date: Available online 25 September 2017
      Source:Comptes Rendus Mathematique
      Author(s): Cédric Dion, Antonio Lei
      We give a new description of Pollack's plus and minus p-adic logarithms log p ± in terms of distributions. In particular, if μ ± denote the pre-images of log p ± under the Amice transform, we give explicit formulae for the values μ ± ( a + p n Z p ) for all a ∈ Z p and all integers n ≥ 1 . Our formulae imply that the distribution μ − agrees with a distribution studied by Koblitz in 1977. Furthermore, we show that a similar description exists for Loeffler's two-variable analogues of these plus and minus logarithms.

  • Restricting uniformly open surjections
    • Abstract: Publication date: Available online 19 September 2017
      Source:Comptes Rendus Mathematique
      Author(s): Tomasz Kania, Martin Rmoutil
      We employ the theory of elementary submodels to improve a recent result by Aron, Jaramillo and Le Donne (2017) [1] concerning restricting uniformly open, continuous surjections to smaller subspaces where they remain surjective. To wit, suppose that X and Y are metric spaces and let f : X → Y be a continuous surjection. If X is complete and f is uniformly open, then X contains a closed subspace Z with the same density as Y such that f restricted to Z is still uniformly open and surjective. Moreover, if X is a Banach space, then Z may be taken to be a closed linear subspace. A counterpart of this theorem for uniform spaces is also established.

      We obtain some recurrence relationships among the partition vectors of the partial exponential Bell polynomials. On using such results, the n-th Adomian polynomial for any nonlinear operator can be expressed explicitly in terms of the partial exponential Bell polynomials. Some new identities for the partial exponential Bell polynomials are obtained by solving certain ordinary differential equations using the Adomian decomposition method.

  • Newton polytopes and symmetric Grothendieck polynomials
    • Abstract: Publication date: August 2017
      Source:Comptes Rendus Mathematique, Volume 355, Issue 8
      Author(s): Laura Escobar, Alexander Yong
      Symmetric Grothendieck polynomials are inhomogeneous versions of Schur polynomials that arise in combinatorial K-theory. A polynomial has saturated Newton polytope (SNP) if every lattice point in the polytope is an exponent vector. We show that the Newton polytopes of these Grothendieck polynomials and their homogeneous components have SNP. Moreover, the Newton polytope of each homogeneous component is a permutahedron. This addresses recent conjectures of C. Monical–N. Tokcan–A. Yong and of A. Fink–K. Mészáros–A. St. Dizier in this special case.

  • On maps which are the identity on the boundary
    • Abstract: Publication date: Available online 6 September 2017

      Author(s): Albert Fathi
      The following fact seems to have been unnoticed until now: Let F be a closed subset of the (finite-dimensional) connected manifold M. If f : F → M is a proper continuous map which is the identity on the boundary ∂F of F in M, then either f ( F ) ⊃ F or f ( F ) ⊃ M ∖ F . The proof is elementary and simple using degree theory. The statement has many deep consequences.

  • On a convergence theorem for semigroups of positive integral operators
    • Abstract: Publication date: Available online 6 September 2017
      Source:Comptes Rendus Mathematique
      Author(s): Moritz Gerlach, Jochen Glück
      We give a new and very short proof of a theorem of Greiner asserting that a positive and contractive C 0 -semigroup on an L p -space is strongly convergent in case it has a strictly positive fixed point and contains an integral operator. Our proof is a streamlined version of a much more general approach to the asymptotic theory of positive semigroups developed recently by the authors. Under the assumptions of Greiner's theorem, this approach becomes particularly elegant and simple. We also give an outlook on several generalisations of this result.

  • Intersection of harmonically weighted Dirichlet spaces

      In 1991, S. Richter introduced harmonically weighted Dirichlet spaces D ( μ ) , motivated by his study of cyclic analytic two-isometries. In this paper, we consider ⋂ μ ∈ P D ( μ ) , the intersection of D ( μ ) spaces, where P is the family of Borel probability measures. Several function-theoretic characterizations of the Banach space ⋂ μ ∈ P D ( μ ) are given. We also show that ⋂ μ ∈ P D ( μ ) is located strictly between some classical analytic Lipschitz spaces and ⋂ μ ∈ P D ( μ ) can be regarded as the endpoint case of analytic Morrey spaces in some sense.

  • A non-perverse Soergel bimodule in type A
    • Abstract: Publication date: Available online 7 August 2017
      Source:Comptes Rendus Mathematique
      Author(s): Nicolas Libedinsky, Geordie Williamson
      A basic question concerning indecomposable Soergel bimodules is to understand their endomorphism rings. In characteristic zero all degree-zero endomorphisms are isomorphisms (a fact proved by Elias and the second author) which implies the Kazhdan–Lusztig conjectures. More recently, many examples in positive characteristic have been discovered with larger degree zero endomorphisms. These give counter-examples to expected bounds in Lusztig's conjecture. Here we prove the existence of indecomposable Soergel bimodules in type A having non-zero endomorphisms of negative degree. This gives the existence of a non-perverse parity sheaf in type A.

      We prove that functions analytic in the unit disk and continuous up to the boundary are dense in the de Branges–Rovnyak spaces induced by the extreme points of the unit ball of H ∞ . Together with previous theorems, it follows that this class of functions is dense in any de Branges–Rovnyak space.

      We establish a new connection between metric Diophantine approximation and the parametric geometry of numbers by proving a variational principle facilitating the computation of the Hausdorff and packing dimensions of many sets of interest in Diophantine approximation. In particular, we show that the Hausdorff and packing dimensions of the set of singular m × n matrices are both equal to m n ( 1 − 1 m + n ) , thus proving a conjecture of Kadyrov, Kleinbock, Lindenstrauss, and Margulis as well as answering a question of Bugeaud, Cheung, and Chevallier. Other applications include computing the dimensions of the sets of points witnessing conjectures of Starkov and Schmidt.

      In the framework of semiclassical resonances, we make more precise the link between the polynomial estimates of the extension of the resolvent and the propagation of the singularities through the trapped set. This approach makes it possible to eliminate infinity and to concentrate the study near the trapped set. It has allowed us in previous papers to obtain the asymptotic of resonances in various geometric situations.

  • Dynamical covering problems on the triadic Cantor set
    • Abstract: Publication date: Available online 28 June 2017
      Source:Comptes Rendus Mathematique
      Author(s): Bao-Wei Wang, Jun Wu, Jian Xu
      In this note, we consider the metric theory of the dynamical covering problems on the triadic Cantor set K . More precisely, let T x = 3 x ( mod 1 ) be the natural map on K , μ the standard Cantor measure and x 0 ∈ K a given point. We consider the size of the set of points in K which can be well approximated by the orbit { T n x 0 } n ≥ 1 of x 0 , namely the set D ( x 0 , φ ) : = { y ∈ K : T n x 0 − y < φ ( n ) for infinitely many n ∈ N } , where φ is a positive function defined on N . It is shown that for μ almost all x 0 ∈ K , the Hausdorff measure of D ( x 0 , φ ) is either zero or full depending upon the convergence or divergence of a certain series. Among the proof, as a byproduct, we obtain an inhomogeneous counterpart of Levesley, Salp and Velani's work on a Mahler's question about the Diophantine approximation on the Cantor set K .

      For a real x ∈ ( 0 , 1 ) ∖ Q , let x = [ a 1 ( x ) , a 2 ( x ) , ⋯ ] be its continued fraction expansion. Denote by T n ( x ) : = max { a k ( x ) : 1 ≤ k ≤ n } the maximum partial quotient up to n. For any real α ∈ ( 0 , ∞ ) , γ ∈ ( 0 , ∞ ) , let F ( γ , α ) : = { x ∈ ( 0 , 1 ) ∖ Q : lim n → ∞ ⁡ T n ( x ) e n γ = α } . For a set E ⊂ ( 0 , 1 ) ∖ Q , let dim H E be its Hausdorff dimension. Recently, Lingmin Liao and Michal Rams showed that dim H F ( γ , α ) = { 1 i f γ ∈ ( 0 , 1 / 2 ) 1 / 2 i f γ ∈ ( 1 / 2 , ∞ ) for any α ∈ ( 0 , ∞ ) . In this paper, we show that dim H F ( 1 / 2 , α ) = 1 / 2 for any α ∈ ( 0 , ∞ ) following Liao and Rams' method, which supplements their result.

  • On the construction of the asymmetric Chudnovsky multiplication algorithm

      The Chudnovsky algorithm for the multiplication in extensions of finite fields provides a bilinear complexity uniformly linear with respect to the degree of the extension. Recently, Randriambololona has generalized the method, allowing asymmetry in the interpolation procedure and leading to new upper bounds on the bilinear complexity. In this note, we describe the construction of this asymmetric method without derived evaluation. To do this, we translate this generalization into the language of algebraic function fields and we give a strategy of construction and implementation.

      It has been proved by Sokolov that Krichever–Novikov equation's hierarchy is hamiltonian for the Hamiltonian operator H 0 = u x ∂ − 1 u x and possesses two weakly non-local recursion operators of degrees 4 and 6, L 4 and L 6 . We show here that H 0 , L 4 H 0 and L 6 H 0 are compatible Hamiltonians operators for which the Krichever–Novikov equation's hierarchy is hamiltonian.
