  • The infinitesimally bendable Euclidean hypersurfaces
    • Authors: M. Dajczer; Th. Vlachos
      Pages: 1961 - 1979
      Abstract: The main purpose of this paper is to complete the work initiated by Sbrana in 1909 giving a complete local classification of the nonflat infinitesimally bendable hypersurfaces in Euclidean space.

  • A subset of Caffarelli–Kohn–Nirenberg inequalities in the hyperbolic
           space $${{\mathbb {H}}}^N$$ H N
    • Authors: Kunnath Sandeep; Cyril Tintarev
      Pages: 2005 - 2021
      Abstract: We prove a subset of inequalities of Caffarelli–Kohn–Nirenberg type in the hyperbolic space \({{\mathbb {H}}^N}, N\ge 2\) , based on invariance with respect to a certain nonlinear scaling group, and study existence of corresponding minimizers. Earlier results concerning the Moser–Trudinger inequality are now interpreted in terms of CKN inequalities on the Poincaré disk.

  • Multiple standing waves for the nonlinear Helmholtz equation concentrating
           in the high frequency limit
    • Authors: Gilles Evéquoz
      Pages: 2023 - 2042
      Abstract: This paper studies for large frequency number \(k>0\) the existence and multiplicity of solutions of the semilinear problem $$\begin{aligned} -\varDelta u -k^2 u=Q(x) u ^{p-2}u\quad \text { in }\mathbb {R}^N, \quad N\ge 2. \end{aligned}$$ The exponent p is subcritical, and the coefficient Q is continuous, nonnegative and satisfies the condition $$\begin{aligned} \limsup _{ x \rightarrow \infty }Q(x)<\sup _{x\in \mathbb {R}^N}Q(x). \end{aligned}$$ In the limit \(k\rightarrow \infty \) , sequences of solutions associated with ground states of a dual equation are shown to concentrate, after rescaling, at global maximum points of the function Q.

  • Multiplicity of positive solutions for a class of fractional Schrödinger
           equations via penalization method
    • Authors: Vincenzo Ambrosio

      Abstract: By using the penalization method and the Ljusternik–Schnirelmann theory, we investigate the multiplicity of positive solutions of the following fractional Schrödinger equation $$\begin{aligned} \varepsilon ^{2s}(-\Delta )^{s} u + V(x)u = f(u)\quad \text{ in } {\mathbb {R}}^{N} \end{aligned}$$ where \(\varepsilon >0\) is a parameter, \(s\in (0, 1)\) , \(N>2s\) , \((-\Delta )^{s}\) is the fractional Laplacian, V is a positive continuous potential with local minimum, and f is a superlinear function with subcritical growth. We also obtain a multiplicity result when \(f(u)= u ^{q-2}u+\lambda u ^{r-2}u\) with \(2<q<2^{*}_{s}\le r\) and \(\lambda >0\) , by combining a truncation argument and a Moser-type iteration.

  • Conformal minimal surfaces immersed into $${\mathbb {H}}P^{n}$$ H P n
    • Authors: Xiaodong Chen; Xiaoxiang Jiao
      Pages: 2063 - 2076
      Abstract: In this paper, we want to construct conformal minimal surfaces and conformal minimal two-spheres in \({\mathbb {H}}P^{n}\) by the twistor map \(\pi : {\mathbb {C}}P^{2n+1} \rightarrow {\mathbb {H}}P^{n}\) . The construction is due to Eells and Wood’s conclusion about the composition of a horizontal harmonic map in 1983. Firstly, we give a characterization of horizontal holomorphic surfaces in \({\mathbb {C}}P^{5}\) . Under this characterization, we construct eight families of conformal minimal surfaces in \({\mathbb {H}}P^{2}\) . Then, we study horizontal Veronese sequences in \({\mathbb {C}}P^{4}\) and \({\mathbb {C}}P^{5}\) , and we transform the construction into solving a quadratic equation. Based on this, we get some examples of conformal minimal two-spheres in \({\mathbb {H}}P^{2}\) with constant curvature \(\frac{4}{5}\) and \(\frac{4}{13}\) .

  • On the cone of strong Kähler with torsion metrics
    • Authors: Michele Maschio
      Pages: 2077 - 2089
      Abstract: This paper examines special metrics on compact complex manifolds, and it is notably focused on the notion of super strong Kähler with torsion metric. This condition is related to the strong Kähler with torsion one in the same manner as the strongly Gauduchon condition is related to the Gauduchon one. Moreover, we provide sufficient and necessary conditions so that every strong Kähler with torsion metric on a compact complex manifold is in fact super strong Kähler with torsion. We prove that these conditions are verified on compact complex manifolds satisfying \(\partial \overline{\partial }\) -lemma but not on 6-dimensional compact complex nilmanifolds.

  • A regularity class for the roots of nonnegative functions
    • Authors: Kolyan Ray; Johannes Schmidt-Hieber
      Pages: 2091 - 2103
      Abstract: We investigate the regularity of the positive roots of a nonnegative function of one-variable. A modified Hölder space \(\mathcal {F}^\beta \) is introduced such that if \(f\in \mathcal {F}^\beta \) then \(f^\alpha \in C^{\alpha \beta }\) . This provides sufficient conditions to overcome the usual limitation in the square root case ( \(\alpha = 1/2\) ) for Hölder functions that \(f^{1/2}\) need be no more than \(C^1\) in general. We also derive bounds on the wavelet coefficients of \(f^\alpha \) , which provide a finer understanding of its local regularity.

  • Existence of martingale solutions and the incompressible limit for
           stochastic compressible flows on the whole space
    • Authors: Prince Romeo Mensah
      Pages: 2105 - 2133
      Abstract: We give an existence and asymptotic result for the so-called finite energy weak martingale solution of the compressible isentropic Navier–Stokes system driven by some random force in the whole spatial region. In particular, given a general nonlinear multiplicative noise, we establish the convergence to the incompressible system as the Mach number, representing the ratio between the average flow velocity and the speed of sound, approaches zero.

  • Characterizing spheres and Euclidean spaces by conformal vector fields
    • Authors: Sharief Deshmukh
      Pages: 2135 - 2145
      Abstract: It is well known that the Euclidean space \( (R^{n},\left\langle ,\right\rangle )\) , the n-sphere \(S^{n}(c)\) of constant curvature c are examples of spaces admitting many conformal vector fields, and therefore conformal vector fields are used in obtaining characterizations of these spaces. In this paper, we use nontrivial conformal vector fields on a compact and connected Riemannian manifold to characterize the sphere \(S^{n}(c)\) . Also, we use a nontrivial conformal vector field on a complete and connected Riemannian manifold and find characterizations for a Euclidean space \((R^{n},\left\langle ,\right\rangle )\) and the sphere \(S^{n}(c)\) .

  • Partial regularity results for non-autonomous functionals with $$\varPhi
           $$ Φ -growth conditions
    • Authors: Flavia Giannetti; Antonia Passarelli di Napoli; Atsushi Tachikawa
      Pages: 2147 - 2165
      Abstract: We prove the partial Hölder continuity of the local minimizers of non-autonomous integral functionals of the type $$\begin{aligned} \int _\varOmega \varPhi \left( \big ( A^{\alpha \beta }_{ij}(x,u) D_iu^\alpha D_ju^\beta \big )^{1/2}\right) \mathrm{d}x, \end{aligned}$$ where \(\varPhi \) is an Orlicz function satisfying both the \(\varDelta _2\) and \(\nabla _2\) conditions and the function \(A(x,s) = \big (A^{\alpha \beta }_{ij}(x,s)\big )\) is uniformly elliptic, bounded and continuous. Assuming in addition that the function \(A(x,s) = \big (A^{\alpha \beta }_{ij}(x,s)\big )\) is Hölder continuous, we prove the partial Hölder continuity also of the gradient of the local minimizers.

  • On a conjecture of De Giorgi related to homogenization
    • Authors: Aram L. Karakhanyan; Henrik Shahgholian
      Pages: 2167 - 2183
      Abstract: For a periodic vector field F, let \(X^\varepsilon \) solve the dynamical system $$\begin{aligned} \frac{{\hbox {d}}{\hbox {X}}^{\varepsilon }}{{\hbox {d}}t} = {{F}}\left( \frac{{X}^{\varepsilon }}{\varepsilon }\right) . \end{aligned}$$ In (Set Valued Anal 2(1–2):175–182, 1994) Ennio De Giorgi enquiers whether from the existence of the limit \( X^0(t):=\lim \nolimits _{\varepsilon \rightarrow 0} X^\varepsilon (t)\) one can conclude that \( \frac{{\hbox {d}} X^0}{{\hbox {d}}t}= {\hbox {constant}}\) . Our main result settles this conjecture under fairly general assumptions on F, which in some cases may also depend on t-variable. Once the above problem is solved, one can apply the result to the corresponding transport equation, in a standard way. This is also touched upon in the text to follow.

  • Stability with respect to actions of real reductive Lie groups
    • Authors: Leonardo Biliotti; Michela Zedda
      Pages: 2185 - 2211
      Abstract: We give a systematic treatment of the stability theory for action of a real reductive Lie group G on a topological space. More precisely, we introduce an abstract setting for actions of noncompact real reductive Lie groups on topological spaces that admit functions similar to the Kempf–Ness function. The point of this construction is that one can characterize stability, semi-stability and polystability of a point by numerical criteria, that is in terms of a function called maximal weight. We apply this setting to the actions of a real noncompact reductive Lie group G on a real compact submanifold M of a Kähler manifold Z and to the action of G on measures of M.

  • Convolvability and regularization of distributions
    • Authors: C. Bargetz; E. A. Nigsch; N. Ortner
      Pages: 2239 - 2251
      Abstract: We apply L. Schwartz’ theory of vector-valued distributions in order to simplify, unify and generalize statements about convolvability of distributions, their regularization properties and topological properties of sets of distributions. The proofs rely on propositions on the multiplication of vector-valued distributions and on the characterization of the spaces \(\mathcal {O}_{M}(E,F)\) and \(\mathcal {O}_{C}'(E,F)\) of multipliers and convolutors for distribution spaces E and F.

  • Two-dimensionality of gravity water flows governed by the equatorial f
           -plane approximation
    • Authors: Calin Iulian Martin
      Pages: 2253 - 2260
      Abstract: We show that gravity wave trains governed by the equatorial f-plane approximation propagate at the free surface of a rotational water flow of constant vorticity vector \((\Omega _1, \Omega _2, \Omega _3)\) over a flat bed only if the flow is two-dimensional. Owing to the presence of Coriolis effects, our result is also true even if the vorticity vector vanishes. This represents a striking difference when compared with the cases without geophysical effects discussed in Constantin (Europhys Lett 86:29001, 2009, Eur J Mech 30:12–16; 2011) and Martin (J Math Fluid Mech 2016. doi:10.1007/s00021-016-0306-1), where the conclusion about the two-dimensionality of the flow was possible under the assumption of constant nonvanishing vorticity vector. Another upshot is that the only nonzero component of the vorticity that may not vanish is \(\Omega _2\) , that is, the one pointing in the horizontal direction orthogonal to the direction of wave propagation.

  • Density of bounded maps in Sobolev spaces into complete manifolds
    • Authors: Pierre Bousquet; Augusto C. Ponce; Jean Van Schaftingen
      Pages: 2261 - 2301
      Abstract: Given a complete noncompact Riemannian manifold \(N^n\) , we investigate whether the set of bounded Sobolev maps \((W^{1, p} \cap L^\infty ) (Q^m; N^n)\) on the cube \(Q^{m}\) is strongly dense in the Sobolev space \(W^{1, p} (Q^m; N^n)\) for \(1 \le p \le m\) . The density always holds when p is not an integer. When p is an integer, the density can fail, and we prove that a quantitative trimming property is equivalent with the density. This new condition is ensured, for example, by a uniform Lipschitz geometry of \(N^{n}\) . As a by-product, we give necessary and sufficient conditions for the strong density of the set of smooth maps \(C^\infty (\overline{Q^m}; N^n)\) in \(W^{1, p} (Q^m; N^n)\) .

  • Global continuation of the eigenvalues of a perturbed linear operator
    • Authors: Pierluigi Benevieri; Alessandro Calamai; Massimo Furi; Maria Patrizia Pera
      Abstract: Let E, F be real Banach spaces and S the unit sphere of E. We study a nonlinear eigenvalue problem of the type \(Lx + \varepsilon N(x) = \lambda Cx\) , where \(\varepsilon ,\lambda \) are real parameters, \(L:E \rightarrow F\) is a Fredholm linear operator of index zero, \(C:E \rightarrow F\) is a compact linear operator, and \(N:S \rightarrow F\) is a compact map. Given a solution \((x,\varepsilon ,\lambda ) \in S \times \mathbb {R}\times \mathbb {R}\) of this problem, we say that the first element x of the triple is a unit eigenvector corresponding to the eigenpair  \((\varepsilon ,\lambda )\) . Assuming that \(\lambda _0 \in \mathbb {R}\) is such that the kernel of \(L -\lambda _0C\) is odd dimensional and a natural transversality condition between the operators \(L -\lambda _0C\) and C is satisfied, we prove that, in the set of all the eigenpairs, the connected component containing \((0,\lambda _0)\) is either unbounded or meets an eigenpair \((0,\lambda _1)\) , with \(\lambda _1 \not = \lambda _0\) . Our approach is topological and based on the classical Leray–Schauder degree.

  • On the local boundedness of generalized minimizers of variational problems
           with linear growth
    • Authors: M. Bildhauer; M. Fuchs; J. Müller; X. Zhong
      Abstract: We prove local boundedness of generalized solutions to a large class of variational problems of linear growth including boundary value problems of minimal surface type and models from image analysis related to the procedure of TV regularization occurring in connection with the denoising of images, which might even be coupled with an inpainting process. Our main argument relies on a Moser-type iteration procedure.
