  • Embeddings of Spherical Homogeneous Spaces
    • Authors: Jacopo Gandini
      Pages: 299 - 340
      Abstract: We review in these notes the theory of equivariant embeddings of spherical homogeneous spaces. Given a spherical homogeneous space G/H, the normal equivariant embeddings of G/H are classified by combinatorial objects called colored fans, which generalize the fans appearing in the classification of toric varieties and which encode several geometric properties of the corresponding variety.

  • Sanya Lectures: Geometry of Spherical Varieties
    • Authors: Nicolas Perrin
      Pages: 371 - 416
      Abstract: These are expanded notes from lectures on the geometry of spherical varieties given in Sanya. We review some aspects of the geometry of spherical varieties. We first describe the structure of B-orbits. Using the local structure theorems, we describe the Picard group and the group of Weyl divisors and give some necessary conditions for smoothness. We later on consider B-stable curves and describe in details the structure of the Chow group of curves as well as the pairing between curves and divisors. Building on these results we give an explicit B-stable canonical divisor on any spherical variety.

  • Orbits of Real Semisimple Lie Groups on Real Loci of Complex Symmetric
           Spaces
    • Authors: Stéphanie Cupit-Foutou; Dmitry A. Timashev
      Pages: 439 - 453
      Abstract: Let G be a complex semisimple algebraic group and X be a complex symmetric homogeneous G-variety. Assume that both G, X as well as the G-action on X are defined over real numbers. Then G(ℝ) acts on X(ℝ) with finitely many orbits. We describe these orbits in combinatorial terms using Galois cohomology, thus providing a patch to a result of Borel and Ji.

  • Standard Embeddings of Smooth Schubert Varieties in Rational Homogeneous
           Manifolds of Picard Number 1
    • Authors: Shin-Young Kim; Kyeong-Dong Park
      Pages: 466 - 487
      Abstract: Smooth Schubert varieties in rational homogeneous manifolds of Picard number 1 are horospherical varieties. We characterize standard embeddings of smooth Schubert varieties in rational homogeneous manifolds of Picard number 1 by means of varieties of minimal rational tangents. In particular, we mainly consider nonhomogeneous smooth Schubert varieties in symplectic Grassmannians and in the 20-dimensional F4-homogeneous manifold associated to a short simple root.

  • Geometric Counting on Wavefront Real Spherical Spaces
    • Authors: Bernhard Krötz; Eitan Sayag; Henrik Schlichtkrull
      Pages: 488 - 531
      Abstract: We provide L p -versus L∞-bounds for eigenfunctions on a real spherical space Z of wavefront type. It is shown that these bounds imply a non-trivial error term estimate for lattice counting on Z. The paper also serves as an introduction to geometric counting on spaces of the mentioned type.

      Abstract: We study two-dimensional irreducible projective smooth algebraic semigroups. Minimal surface semigroups with Kodaira dimension at most one are partially classified. We also calculate the local dimension of the moduli scheme parameterizing all algebraic semigroup laws on a fixed minimal surface.

  • The Log Minimal Model Program for Horospherical Varieties Via Moment
           Polytopes
    • Authors: Boris Pasquier
      Pages: 542 - 562
      Abstract: In a previous work, we described the Minimal Model Program in the family of ℚ-Gorenstein projective horospherical varieties, by studying certain continuous changes of moment polytopes of polarized horospherical varieties. Here, we summarize the results of the previous work and we explain how to generalize them in order to describe the Log Minimal Model Program for pairs (X, Δ) when X is a projective horospherical variety.

  • On Some Families of Smooth Affine Spherical Varieties of Full Rank
    • Authors: Kay Paulus; Guido Pezzini; Bart Van Steirteghem
      Pages: 563 - 596
      Abstract: Let G be a complex connected reductive group. Losev has shown that a smooth affine spherical G-variety X is uniquely determined by its weight monoid, which is the set of irreducible representations of G that occur in the coordinate ring of X. In this paper we use a combinatorial characterization of the weight monoids of smooth affine spherical varieties to classify: (a) all such varieties for G = SL(2) × ℂ × and (b) all such varieties for G simple which have a G-saturated weight monoid of full rank. We also use the characterization and Knop’s classification theorem for multiplicity free Hamiltonian manifolds to give a new proof of Woodward’s result that every reflective Delzant polytope is the moment polytope of such a manifold.

  • Multiple forced rotational solutions for the planar N -pendulum equation
    • Authors: Hui Qiao
      Pages: 171 - 193
      Abstract: This paper presents a theorem of existence of \((N - N_{0} + 1)2^{N_{0}}\) noncontractible periodic orbits of any given rotational vector with zero components for the planar forced N-pendulum equation, where N 0 denotes the number of zero components of given rotational vector. We make special arrangements for masses and length instead of the nondegenerate assumption. Moreover, for rotational vectors with identical components, similar results is also obtained.

  • Topological entropy of a graph map
    • Authors: Tai Xiang Sun
      Pages: 194 - 208
      Abstract: Let G be a graph and f: G → G be a continuous map. Denote by h(f), P(f),AP(f),R(f) and ω(x, f) the topological entropy of f, the set of periodic points of f, the set of almost periodic points of f, the set of recurrent points of f and the ω-limit set of x under f, respectively. In this paper, we show that the following statements are equivalent: (1) h(f) > 0. (2) There exists an x ∈ G such that ω(x, f) ∩ P(f) ≠ Ø and ω(x, f) is an infinite set. (3) There exists an x ∈ G such that ω(x, f) contains two minimal sets. (4) There exist x, y ∈ G such that ω(x, f) − ω(y, f) is an uncountable set and ω(y, f) ∩ ω(x, f) ≠ Ø. (5) There exist an x ∈ G and a closed subset A ⊂ ω(x, f) with f(A) ⊂ A such that ω(x, f) − A is an uncountable set. (6) R(f) − AP(f) ≠ Ø. (7) f P ( f ) is not pointwise equicontinuous.

  • On the Sobolev boundedness results of the product of pseudo-differential

    • Authors: Akhilesh Prasad; Kanailal Mahato
      Pages: 221 - 232
      Abstract: This article is concerned with the study of pseudo-differential operators associated with fractional Hankel transform. The product of two fractional pseudo-differential operators is defined and investigated its basic properties on some function space. It is shown that the pseudo-differential operators and their products are bounded in Sobolev type spaces. Particular cases are discussed.

  • Homogenization of hyperbolic damped stochastic wave equations
    • Authors: Aurelien Fouetio; Jean Louis Woukeng
      Pages: 233 - 254
      Abstract: For a family of linear hyperbolic damped stochastic wave equations with rapidly oscillating coefficients, we establish the homogenization result by using the sigma-convergence method. This is achieved under an abstract assumption covering special cases like the periodicity, the almost periodicity and some others.

  • Neighbor sum distinguishing colorings of graphs with maximum average
           degree less than $$\tfrac{{37}} {{12}}$$ 37 12
    • Authors: Bao Jian Qiu; Ji Hui Wang; Yan Liu
      Pages: 265 - 274
      Abstract: Let G be a graph and let its maximum degree and maximum average degree be denoted by Δ(G) and mad(G), respectively. A neighbor sum distinguishing k-edge colorings of graph G is a proper k-edge coloring of graph G such that, for any edge uv ∈ E(G), the sum of colors assigned on incident edges of u is different from the sum of colors assigned on incident edges of v. The smallest value of k in such a coloring of G is denoted by χ′∑(G). Flandrin et al. proposed the following conjecture that χ′∑ (G) ≤ Δ(G) + 2 for any connected graph with at least 3 vertices and G ≠ C 5. In this paper, we prove that the conjecture holds for a normal graph with mad(G) < \(\tfrac{{37}} {{12}}\) and Δ(G) ≥ 7.

      Abstract: The Sarason’s Toeplitz product problem asks when the Toeplitz product operator T u T v̅ , with analytic symbols u and v, is bounded on Hilbert space of analytic functions. In this paper, we deal with this problem on the Fock–Sobolev space and have a complete solution that u = e q , v = Ce −q , where q is a linear complex polynomial and C is a nonzero constant.
