  • Multilinear singular integral operators with generalized kernels and their
           multilinear commutators
    • Authors: Yan Lin; Ya Yuan Xiao
      Pages: 1443 - 1462
      Abstract: In this paper, the authors study a class of multilinear singular integral operators with generalized kernels and their multilinear commutators with BMO functions. By establishing the sharp maximal estimates, the boundedness on product of weighted Lebesgue spaces and product of variable exponent Lebesgue spaces is obtained, respectively. Moreover, the endpoint estimate of this class of mutilinear singular integral operators is also established. These results can improve the corresponding known results of classical multilinear Calderón–Zygmund operators and multilinear Calderón–Zygmund operators with Dini type kernels.

  • Relative singularity categories with respect to gorenstein flat modules
    • Authors: Zhen Xing Di; Zhong Kui Liu; Xiao Xiang Zhang
      Pages: 1463 - 1476
      Abstract: Let R be a right coherent ring and D b (R-Mod) the bounded derived category of left R-modules. Denote by \({D^b}{\left( {R - Mod} \right)_{\widehat {\left[ {GF,C} \right]}}}\) the subcategory of D b (R-Mod) consisting of all complexes with both finite Gorenstein flat dimension and cotorsion dimension and K b (F ∩ C) the bounded homotopy category of flat cotorsion left R-modules. We prove that the quotient triangulated category \({D^b}{\left( {R - Mod} \right)_{\widehat {\left[ {GF,C} \right]}}}\) /K b (F ∩ C) is triangle-equivalent to the stable category GF ∩ C of the Frobenius category of all Gorenstein flat and cotorsion left R-modules.

  • On a classical theorem on the diameter and minimum degree of a graph
    • Authors: Verónica Hernández; Domingo Pestana; José M. Rodríguez
      Pages: 1477 - 1503
      Abstract: In this work, we obtain good upper bounds for the diameter of any graph in terms of its minimum degree and its order, improving a classical theorem due to Erdös, Pach, Pollack and Tuza. We use these bounds in order to study hyperbolic graphs (in the Gromov sense). To compute the hyperbolicity constant is an almost intractable problem, thus it is natural to try to bound it in terms of some parameters of the graph. Let H(n, δ 0) be the set of graphs G with n vertices and minimum degree δ 0, and J(n, Δ) be the set of graphs G with n vertices and maximum degree Δ. We study the four following extremal problems on graphs: a(n, δ 0) = min{δ(G) G ∈ H(n, δ 0)}, b(n, δ 0) = max{δ(G) G ∈ H(n, δ 0)}, α(n, Δ) = min{δ(G) G ∈ J(n, Δ)} and β(n, Δ) = max{δ(G) G ∈ J(n, Δ)}. In particular, we obtain bounds for b(n, δ 0) and we compute the precise value of a(n, δ 0), α(n, Δ) and β(n, Δ) for all values of n, δ 0 and Δ, respectively.

      Abstract: Let b(n) denote the number of cubic partition pairs of n. In this paper, we aim to provide a strategy to obtain arithmetic properties of b(n). This gives affirmative answers to two of Lin’s conjectures.

  • Analytic properties for holomorphic matrix-valued maps in ℂ 2×2
    • Authors: Chao Fu; Ye Zhou Li; Xiao Yao
      Pages: 1536 - 1548
      Abstract: In this paper, we investigate some analytic properties for a class of holomorphic matrixvalued functions. In particular, we give a Picard type theorem which depicts the characterization of Picard omitting value in these functions. We also study the relation between asymptotic values and Picard omitting values, and the relation between periodic orbits of the canonical extension on ℂ2×2 and Julia set of one dimensional complex dynamic system.

  • On the existence, uniqueness and stability of solutions for semi-linear
           generalized elasticity equation with general damping term
    • Authors: Abita Rahmoune
      Pages: 1549 - 1564
      Abstract: In this paper, we consider a semi-linear generalized hyperbolic boundary value problem associated to the linear elastic equations with general damping term and nonlinearities of variable exponent type. Under suitable conditions, local and global existence theorems are proved. The uniqueness of the solution have been gotten by eliminating some hypotheses that have been imposed by other authors for different particular problems. We show that any solution with nontrivial initial datum becomes stable.

  • Avramov–Martsinkovsky type exact sequences with tor functors

      Abstract: For two classes of right R-modules W, X such that P ⊂ W ⊂ X, where P is the class of projective right R-modules, we show that there is an Avramov–Martsinkovsky type exact sequence with generalized Tate homology functor \({\widehat {Tor}^{X.W}}\) , relative homology functors Tor W and Tor X . Many results in Iacob [Comm. Algebra, 35, 1589–1606 (2007)] and Liang [Algebr. Represent. Theory, 16, 1541–1560 (2013)] are generalized and improved.

  • Recursion relations for the constrained multi-component KP hierarchy

      Pages: 1578 - 1586
      Abstract: In this paper, we define a new constrained multi-component KP(cMKP) hierarchy which contains the constrained KP(cKP) hierarchy as a special case. We derive the recursion operator of the constrained multi-component KP hierarchy. As a special example, we also give the recursion operator of the constrained two-component KP hierarchy.

  • Sewing homeomorphism and conformal invariants
    • Authors: Tao Cheng; Hui Qiang Shi; Shanshuang Yang
      Pages: 1321 - 1338
      Abstract: This paper is devoted to the study of some fundamental properties of the sewing homeomorphism induced by a Jordan domain. In particular, using conformal invariants such as harmonic measure, extremal distance, and reduced extremal distance, we give several necessary and sufficient conditions for the sewing homeomorphism to be bi-Lipschitz or bi-Hölder. Furthermore, equivalent conditions for a Jordan curve to be a quasicircle are also obtained.

  • On the asymptotically PT −1 spaces

      Pages: 1421 - 1430
      Abstract: In this note, first, we show that the asymptotic subcone, the ultralimit, the completion of an asymptotically PT−1 space are still an asymptotically PT−1 space. Secondly, we consider two kinds of metric spaces, which have been considered by Ibragimov and Gromov, respectively. We show that they are asymptotically PT−1 spaces under particular conditions, which provide some concrete examples of asymptotically PT−1 spaces.

  • Isometries and additive mapping on the unit spheres of normed spaces
    • Authors: Rui Dong Wang; Xu Jian Huang
      Pages: 1431 - 1442
      Abstract: In this paper, we investigate isometric extension problem in general normed space. We prove that an isometry between spheres can be extended to a linear isometry between the spaces if and only if the natural positive homogeneous extension is additive on spheres. Moreover, this conclusion still holds provided that the additivity holds on a restricted domain of spheres.

  • On the fourth power moment of Fourier coefficients of cusp form

      Abstract: Let a(n) be the Fourier coefficients of a holomorphic cusp form of weight κ = 2n ≥ 12 for the full modular group and A(x) = Ʃ n ≤ x a(n). In this paper, we establish an asymptotic formula of the fourth power moment of A(x) and prove that \(\int_1^T {{A^4}\left( x \right)dx = \frac{3}{{64\kappa {\pi ^4}}}{s_{4;2}}\left( {\tilde a} \right){T^{2\kappa }} + O\left( {{T^{2\kappa - {\delta _4} + \varepsilon }}} \right)} \) with δ4 = 1/8, which improves the previous result.

  • On the characterization of maximal planar graphs with a given signed cycle
           domination number
    • Authors: Xiao Ming Pi
      Abstract: Let G = (V,E) be a simple graph. A function f: E → {+1,−1} is called a signed cycle domination function (SCDF) of G if Ʃ e∈E(C) f(e) ≥ 1 for every induced cycle C of G. The signed cycle domination number of G is defined as γ′sc(G) = min{Ʃ e∈E f(e) f is an SCDF of G}. This paper will characterize all maximal planar graphs G with order n ≥ 6 and γ′sc(G) = n.

  • Non-trivially graded self-dual fusion categories of rank 4
    • Authors: Jing Cheng Dong; Liang Yun Zhang; Li Dai
      Abstract: Let C be a self-dual spherical fusion categories of rank 4 with non-trivial grading. We complete the classification of Grothendieck ring K(C) of C; that is, we prove that K(C) ≅= Fib⊗Z[Z2], where Fib is the Fibonacci fusion ring and Z[Z2] is the group ring on Z2. In particular, if C is braided, then it is equivalent to Fib⊠ \(Vec_{{\mathbb{Z}_2}}^\omega \) as fusion categories, where Fib is a Fibonacci category and \(Vec_{{\mathbb{Z}_2}}^\omega \) is a rank 2 pointed fusion category.

  • Multiple forced rotational solutions for the planar N -pendulum equation
    • Authors: Hui Qiao
      Abstract: This paper presents a theorem of existence of (N − N 0 + 1)2 N0 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.

      Abstract: In this paper, the famous logistic map is studied in a new point of view. We study the boundedness and the periodicity of non-autonomous logistic map $${x_{n + 1}} = {r_n}{x_n}\left( {1 - {x_n}} \right),n = 0,1, \ldots ,$$ where {r n } is a positive p-periodic sequence. The sufficient conditions are given to support the existence of asymptotically stable and unstable p-periodic orbits. This appears to be the first study of the map with variable parameter r.

  • On p -convergent operators on Banach lattices
    • Authors: Elroy D. Zeekoei; Jan H. Fourie
      Abstract: The notion of a p-convergent operator on a Banach space was originally introduced in 1993 by Castillo and Sánchez in the paper entitled “Dunford–Pettis-like properties of continuous vector function spaces”. In the present paper we consider the p-convergent operators on Banach lattices, prove some domination properties of the same and consider their applications (together with the notion of a weak p-convergent operator, which we introduce in the present paper) to a study of the Schur property of order p. Also, the notion of a disjoint p-convergent operator on Banach lattices is introduced, studied and its applications to a study of the positive Schur property of order p are considered.
