    Stochastic Maximum Principle for Square-Integrable Optimal Control of Linear Stochastic Systems

    Shanjian TANGXueqi WANG
    661-676页
    查看更多>>摘要：The authors give a stochastic maximum principle for square-integrable optimal control of linear stochastic systems.The control domain is not necessarily convex and the cost functional can have a quadratic growth.In particular,they give a stochastic maximum principle for the linear quadratic optimal control problem.

    Holomorphic Connections and Problems of Lifts

    Arif SALIMOVNarmina GURBANOVA
    677-684页
    查看更多>>摘要：Considering the bundle of 2-jets as a realization of the holomorphic manifold over 3-dimensional nilpotent algebra,the authors introduce a new class of lifts of connec-tions in the bundle of 2-jets which is a generalization of the complete lifts.

    Bresse Beam with Damping and Logarithmic Source

    Sebasti?o CORDEIROCarlos BALDEZCarlos RAPOSODucival PEREIRA...
    685-702页
    查看更多>>摘要：This paper investigates the stabilization of a Bresse system with internal damp-ing and logarithmic source.The authors use the potential well theory.For initial data in the stability set created by the Nehari surface,the existence of a global solution is proved by using Faedo-Galerkin's approximation.The Nakao theorem gives the exponential decay.A numerical approach is presented to illustrate the results obtained.

    Fixed Subgroups are not Compressed in Direct Products of Surface Groups

    Qiang ZHANGJianchun WUFanling GU
    703-708页
    查看更多>>摘要：By constructing counterexamples,the authors show that the fixed subgroups are not compressed in direct products of free and surface groups,and hence negate a conjecture in[Zhang,Q.,Ventura,E.and J.Wu,Fixed subgroups are compressed in surface groups,Internat.J.Algebra Comput.,25,2015,865-887].

    On the Turán Numbers of Linear Forests in Bipartite Graphs

    Tianying XIELongtu YUAN
    709-732页
    查看更多>>摘要：A linear forest is a graph consisting of paths.In this paper,the authors determine the maximum number of edges in an(m,n)-bipartite graph which does not contain a linear forest consisting of paths on at least four vertices for n ≥ m when m is sufficiently large.

    733-766页
    查看更多>>摘要：Edge-to-edge tilings of the sphere by congruent a2bc-quadrilaterals are classified as 3 classes:(1)A 1-parameter family of quadrilateral subdivisions of the octahedron with 24 tiles,and a flip modification for one special parameter;(2)a 2-parameter family of 2-layer earth map tilings with 2n tiles for each n ≥ 3;(3)a 3-layer earth map tiling with 8n tiles for each n ≥ 2,and two flip modifications for each odd n.The authors also describe the moduli of parameterized tilings and provide the full geometric data for all tilings.

    A Study on the Second Order Tangent Bundles over Bi-K?hlerian Manifolds

    Nour Elhouda DJAAAydin GEZERAbderrahim ZAGANE
    777-804页
    查看更多>>摘要：This paper aims to study the Berger type deformed Sasaki metric gBs on the second order tangent bundle T2M over a bi-Kählerian manifold M.The authors firstly find the Levi-Civita connection of the Berger type deformed Sasaki metric gBS and calculate all forms of Riemannian curvature tensors of this metric.Also,they study geodesics on the second order tangent bundle T2M and bi-unit second order tangent bundle T21,1M,and characterize a geodesic of the bi-unit second order tangent bundle in terms of geodesic curvatures of its projection to the base.Finally,they present some conditions for a sectionσ:M → T2M to be harmonic and study the harmonicity of the different canonical projections and inclusions of(T2M,gBs).Moreover,they search the harmonicity of the Berger type deformed Sasaki metric gBs and the Sasaki metric gs with respect to each other.

    Exact Convergence Rate of the Local Limit Theorem for a Branching Random Walk in Zd with a Random Environment in Time

    Jian-xin LIUZhi-qiang GAO
    805-822页
    查看更多>>摘要：Consider a branching random walk with a random environment in time in the d-dimensional integer lattice.The branching mechanism is governed by a supercritical branching process,and the particles perform a lazy random walk with an independent,non-identical increment distribution.For A ⊂ Zd,let Zn(A)be the number of offsprings of generation n located in A.The exact convergence rate of the local limit theorem for the counting measure Zn(·)is obtained.This partially extends the previous results for a simple branching random walk derived by Gao(2017,Stoch.Process Appl.).
