摘要
本文研究一类加性白噪声驱动的具有时滞的随机格动力系统的动力学。引入Xρ空间,运用Hilbert空间中的基本等式和Young、Gronwall、Schwarz不等式,证明了随机时滞格点方程解的存在性、唯一性和对初值的连续依赖性,从而得到其解生成连续的无穷维随机动力系统。
The dynamics of a class of stochastic lattice dynamical systems with time delay driven by additive white noise is studied.Xρspace is introduced,basic equalities,Young inequality,Gronwall inequality and Schwarz inequality are applied.The existence,uniqueness and continuous dependence on the initial data of solutions to the stochastic delay lattice equations with additive noise are presented.Then a continuous infinite dimensional random dynamical system generated by the solutions is obtained.
