  • Well-posedness and Blow-up Phenomena for the Cross-coupled
           Camassa–Holm System
    • Authors: Zhiqiang Wei
      Pages: 49 - 61
      Abstract: In this paper, we investigate the cross-coupled Camassa–Holm system. First, we prove local well-posedness for the cross-coupled Camassa–Holm equations in \(H^s ({\mathbb {R}})\) with \(s > 3/2\) . Then, a blow-up criterion is established.

  • The Distribution of Zeros of Solutions of Advanced Dynamic Equations on
           Time Scales
    • Authors: Hongwu Wu
      Pages: 63 - 79
      Abstract: This paper is concerned with the distribution of zeros of solutions of first-order linear advanced dynamic equations. By introducing a class of sequences involving iterates of the argument, some estimates for the distances between consecutive zeros of solutions are obtained on arbitrary time scales. Our results improve those for differential equations, and provide new results on the distribution of zeros of solutions for arbitrary time scales. Some examples are given to illustrate our results.

  • Prevalence Problem in the Set of Quadratic Stochastic Operators Acting on
           $$L^{1}$$ L 1
    • Authors: Krzysztof Bartoszek; Małgorzata Pułka
      Pages: 159 - 173
      Abstract: This paper is devoted to the study of the problem of prevalence in the class of quadratic stochastic operators acting on the \(L^{1}\) space for the uniform topology. We obtain that the set of norm quasi-mixing quadratic stochastic operators is a dense and open set in the topology induced by a very natural metric. This shows the typical long-term behaviour of iterates of quadratic stochastic operators.

      Pages: 175 - 190
      Abstract: We prove some inequalities involving fourth central moment of a random variable that takes values in a given finite interval. Both discrete and continuous cases are considered. Bounds for the spread are obtained when a given \(n\times n\) complex matrix has real eigenvalues. Likewise, we discuss bounds for the spans of polynomial equations.

  • The Shortest Path Problem for the Distant Graph of the Projective Line
           Over the Ring of Integers
    • Authors: Andrzej Matraś; Artur Siemaszko
      Pages: 231 - 248
      Abstract: The distant graph \(G=G({\mathbb {P}}(Z), \vartriangle )\) of the projective line over the ring of integers is considered. The shortest path problem in this graph is solved by use of Klein’s geometric interpretation of Euclidean continued fractions. In case the minimal path is non-unique, all the possible splitting are described which allows us to give necessary and sufficient conditions for existence of a unique shortest path.

  • Positive Solutions of Singular Fractional Boundary Value Problem with
           p-Laplacian
    • Authors: Dehong Ji
      Pages: 249 - 263
      Abstract: In this paper, we present some new results concerning positive solutions for the singular fractional boundary value problem with p-Laplacian. By imposing some suitable conditions on the nonlinear term f,  existence results of positive solutions are obtained. The proof is based upon theory of Leray–Schauder degree. The interesting point is the nonlinear term f(t, u) may be singular at \(u=0\) .

  • Measure Theory and Square-Mean Pseudo Almost Periodic and Automorphic
           Process: Application to Stochastic Evolution Equations
    • Authors: Mamadou Abdoul Diop; Khalil Ezzinbi; Mamadou Moustapha Mbaye
      Pages: 287 - 310
      Abstract: In this work, we establish a new concept of square-mean pseudo almost periodic and automorphic processes using the measure theory. We use the \({\mu }\!-\) ergodic process to define the spaces of \({\mu }\!-\) pseudo almost periodic and automorphic processes in the square-mean sense. We establish many interesting results on those spaces like completeness and composition theorems. Then, we study the existence, the uniqueness, and the stability of the square-mean \({\mu }\!-\) pseudo almost periodic and automorphic solutions of the stochastic evolution equation. We provide an example to illustrate ours results.

  • Classification of the Toroidal Jacobson Graphs
    • Authors: H. Amraei; H. R. Maimani; M. R. Pournaki; A. Zaeembashi
      Pages: 321 - 334
      Abstract: Let R be a finite commutative ring with nonzero identity and denote its Jacobson radical by J(R). The Jacobson graph of R is the graph in which the vertex set is \(R\setminus J(R)\) , and two distinct vertices x and y are adjacent if and only if \(1-xy\) is not a unit in R. In this paper, up to isomorphism, we classify the rings R whose Jacobson graphs are toroidal.

  • ( A ,  m )-Isometric Unilateral Weighted Shifts in Semi-Hilbertian
           Spaces
    • Authors: R. Rabaoui; A. Saddi
      Pages: 371 - 392
      Abstract: For a positive integer m, a bounded linear operator T on a Hilbert space \(\mathbb {H}\) is called an (A, m)-isometry, if \(\Theta ^{(m)}_{A}(T) =\sum _{k=0}^{m}(-1)^{m-k}{m\atopwithdelims ()k}T^{*k}AT^{k}=0\) , where A is a positive (semi-definite) operator. In this paper we give a characterization of (A, m)-isometric and strict (A, m)-isometric unilateral weighted shifts in terms of their weight sequences, respectively. Moreover, we characterize (A, 2)-expansive unilateral weighted shifts (i.e. operators satisfying \(\Theta ^{(2)}_{A}(T)\le 0\) ).

  • On (Strong) Proper Vertex-Connection of Graphs
    • Authors: Hui Jiang; Xueliang Li; Yingying Zhang; Yan Zhao
      Pages: 415 - 425
      Abstract: A path in a vertex-colored graph is a vertex-proper path if any two internal adjacent vertices differ in color. A vertex-colored graph is proper vertex k-connected if any two vertices of the graph are connected by k disjoint vertex-proper paths of the graph. For a k-connected graph G, the proper vertex k-connection number of G, denoted by \(pvc_{k}(G)\) , is defined as the smallest number of colors required to make G proper vertex k-connected. A vertex-colored graph is strong proper vertex-connected, if for any two vertices u, v of the graph, there exists a vertex-proper u-v geodesic. For a connected graph G, the strong proper vertex-connection number of G, denoted by spvc(G), is the smallest number of colors required to make G strong proper vertex-connected. These concepts are inspired by the concepts of rainbow vertex k-connection number \(rvc_k(G)\) , strong rainbow vertex-connection number srvc(G), and proper k-connection number \(pc_k(G)\) of a k-connected graph G. Firstly, we determine the value of pvc(G) for general graphs and \(pvc_k(G)\) for some specific graphs. We also compare the values of \(pvc_k(G)\) and \(pc_k(G)\) . Then, sharp bounds of spvc(G) are given for a connected graph G of order n, that is, \(0\le spvc(G)\le n-2\) . Moreover, we characterize the graphs of order n such that \(spvc(G)=n-2,n-3\) , respectively. Finally, we study the relationship among the three vertex-coloring parameters, namely, \(spvc(G), \ srvc(G)\) , and the chromatic number \(\chi (G)\) of a connected graph G.

  • Stability Analysis of Fuzzy Genetic Regulatory Networks with Various Time
           Delays
    • Authors: K. Ratnavelu; M. Kalpana; P. Balasubramaniam
      Pages: 491 - 505
      Abstract: The synthetic genetic regulatory networks (GRNs) prove to be a powerful tool in studying gene regulation processes in living organisms. In order to take vagueness into consideration, fuzzy theory is incorporated in the GRNs and we found a novel system, namely fuzzy genetic regulatory networks (FGRNs). By applying the Homeomorphism theorem, we demonstrated an existence, uniqueness, and asymptotic stability analysis of the equilibrium point of FGRNs with time delay in the leakage term and unbounded distributed delays. By utilizing Lyapunov functional method and the linear matrix inequality (LMI) techniques, some new and useful criteria of the FGRNs with respect to the equilibrium point are derived. The derived criteria are of the form of LMI, and hence they can be verified easily. Finally, illustrative example with simulations are demonstrated to prove the effectiveness of the proposed results.

  • Some Simple Criteria for the Solvability of Block $$2 \times 2$$ 2 × 2
           Linear Systems
    • Authors: Yongxin Yuan; Kezheng Zuo; Hao Liu; Wenhua Zhao
      Abstract: In many areas, there arise linear systems of the form $$\begin{aligned} \left[ \begin{array}{ll} A &{}\quad B^\top \\ B &{}\quad -\,D \\ \end{array} \right] \left[ \begin{array}{c} x \\ y \\ \end{array} \right] =\left[ \begin{array}{c} f \\ g \\ \end{array} \right] , \end{aligned}$$ where \(A \in {\mathbf {R}}^{n\times n}, D \in {\mathbf {R}}^{p\times p}\) are symmetric and positive semi-definite and \(B \in {\mathbf {R}}^{p \times n}.\) In this paper, some simple criteria for this special linear systems to have solutions and the unique solution are provided, and the solvability conditions are expressed by \(A, B, D, f\) and \(g\) .

  • The Rank of the Semigroup of All Order-Preserving Transformations on a
           Finite Fence
    • Authors: Vítor H. Fernandes; Jörg Koppitz; Tiwadee Musunthia
      Abstract: A zig-zag (or fence) order is a special partial order on a (finite) set. In this paper, we consider the semigroup \(\mathscr {TF}_{n}\) of all order-preserving transformations on an n-element zig-zag-ordered set. We determine the rank of \(\mathscr {TF}_{n}\) and provide a minimal generating set for \( \mathscr {TF}_{n}\) . Moreover, a formula for the number of idempotents in \(\mathscr {TF}_{n}\) is given.

  • Global Power Stability of Neural Networks with Impulses and Proportional
           Delays
    • Authors: Kaizhong Guan
      Abstract: By establishing two new impulsive delay differential inequalities from impulsive perturbation and impulsive control point of view, respectively, constructing some Lyapunov functionals, and employing the matrix measure approach, some novel and sufficient conditions are obtained to guarantee global power stability of neural networks with impulses and proportional delays. The obtained stability criteria are dependent on impulses and the proportional delay factor so that it is convenient to derive some feasible impulsive control laws according to the proportional delay factor allowed by such neural networks. It is shown that impulses can act as stabilizers to globally power stabilize an unstable neural network with proportional delay based on suitable impulsive control laws. Moreover, the power convergence rate can be estimated and obtained by simple computation. Three numerical examples are given to illustrate the effectiveness and advantages of the results obtained.

  • Forward–Backward Splitting Method for Solving a System of
           Quasi-Variational Inclusions
    • Authors: Shih-Sen Chang; Ching-Feng Wen; Jen-Chih Yao
      Abstract: The purpose of this paper is by using a generalized forward–backward splitting method to propose an iterative algorithm for finding a common element of the set of solutions to a system of quasi-variational inclusions with accretive mappings and the set of fixed points for a \(\lambda \) -strictly pseudo-contractive mapping in Banach spaces. Some strong convergence theorems of the sequence generated by the algorithm are proved. The results presented in the paper extend and improve some recent results. As applications, we utilize our results to study the approximation problem of solutions to a system of variational inequalities, accretive variational inequality problem and convex minimization problem in Banach spaces.

  • Automorphism Group of the Subspace Inclusion Graph of a Vector Space
    • Authors: Xinlei Wang; Dein Wong
      Abstract: In a recent paper, Das introduced the graph \(\mathcal {I}n(\mathbb {V})\) , called subspace inclusion graph on a finite dimensional vector space \(\mathbb {V}\) , where the vertex set is the collection of nontrivial proper subspaces of \(\mathbb {V}\) and two vertices are adjacent if one is properly contained in another. Das studied the diameter, girth, clique number and chromatic number of \(\mathcal {I}n(\mathbb {V})\) when the base field is arbitrary, and he also studied some other properties of \(\mathcal {I}n(\mathbb {V})\) when the base field is finite. At the end of the above paper, the author posed the open problem of determining the automorphisms of \(\mathcal {I}n(\mathbb {V})\) . In this paper, we give the answer to the open problem.

  • Quasi-exact Sequences of S -Acts
    • Authors: Reza Aminizadeh; Hamid Rasouli; Abolfazl Tehranian
      Abstract: In this paper, the notion of (short) quasi-exact sequence of S-acts is introduced. We study the behaviour of quasi-exact sequences in regard to some algebraic properties of S-acts including principal weak injectivity, principal weak flatness, regularity and torsion freeness. Moreover, some results concerning commutative diagrams of modules are generalized to acts over monoids.
