Abstract:The paper is devoted to the long term asymptoticbehavior of solutions to the stochastic Zakharov lattice equationswith multiplicative white noise. Firstly, using Ornstein-Uhlenbeck transformation, the stochastic Zakharov lattice system is turned into a random differential equation with random coefficients, testify theexistence and uniqueness of solutions, therefore the solution of the system determine a continuous random dynamical system withtempered random absorbing set, in which the random dynamical system is asymptotically compactness, then obtain random attractor and absorbing all tempered random sets. | |||

Abstract:Since many results on existence of continuous iterative roots were obtained, stability of iterative roots becomes an important subject in order to compute iterative roots numerically. This paper discusses on continuous stability and continuously differentiable stability of monotone iterative roots, showing results of the Hyers-Ulam stability, results of approximation which actually give continuous stability, and a comparison between local continuously differentiable stablility and global continuously differentiable unstability for iterative roots. | |||

Abstract:This paper defines the pressure for asymptotically sub-additive potentials under a mistake function, including the measure-theoretical and the topological versions. Using the advanced techniques of ergodic theory and topological dynamics, we reveal a variational principle for the new defined topological pressure without any additional conditions on the potentials and the compact metric space. | |||

Abstract:In this letter, the modified projective synchronization between two fractional-order chaotic systems with different dimensions is investigated. The added-order scheme and the reduced-order scheme are proposed, respectively. Based on the Laplace transformation and feedback control theory, controllers are designed such that two chaotic systems with different dimensions could be synchronized asymptotically under the presented schemes. Corresponding numerical simulations are given to show the effectiveness of the proposed schemes. | |||

Abstract:In this paper, we consider one-dimensional (1D) nonlinear 2k order wave equations under the Dirichlet boundary conditions, weher the nonlinearity f is an analytic, odd function. It is proved that for almost all real pa-rameters m>0, the equations admit small-amplitude quasi-periodic solutionscorresponding to finite dimensional invariant tori for an associated infnite dimensional dynamical system. The proof is based on an infnite dimensional KAM theory and apartial Birkhoff normal form technique. | |||

Abstract:In this paper we study the center problem and the limit cycle bifurcation of switching differential systems. Computing the generalized Lyapunov constants and decomposing their variety, we obtain the center condition of a switching quadratic system. Moreover, developing Christopher's method of finding limit cycles near centers for analytic systems, we prove that there are perturbations having 9 limit cycles near the center at the origin of the considered switching quadratic system. | |||

Abstract:In this paper, we review Morse decomposition and Lyapunov functions. Most of the results are due to Conley and are known. Attractor-repeller pairs and Morse decompositions are very useful to study the inner structure of invariant sets for given dynamical systems. Lyapunov functions is helpful for us to study the stability of dynamical systems. We will review the relations between them. | |||

Abstract:It is well-known that Morse decomposition is very useful to study the inner structure of invariant sets for given dynamical systems. Recently, Morse decomposition is established for random dynamical systems, which can be used to investigate the inner structure of random invariant sets, e.g. random attractors. In this note, we review Morse decomposition theorem for random dynamical systems. | |||
