In this paper, based on the properties of almost periodic function and exponential dichotomy of linear system on time scales as well as Krasnoselskii’s fixed point theorem, some sufficient conditions are established for the existence of square-mean almost periodic solutions of neutral stochastic functional differential equations on time scales. Finally, an example is presented to illustrate the...
in a real separable Hilbert space H driven by an infinite dimensional cylindrical symmetric Lévy process Z = (Zt). The process Z may take values in a Hilbert space 1 Supported by the M.I.U.R. research projects Prin 2004 and 2006 “Kolmogorov equations” and by the Polish Ministry of Science and Education project 1PO 3A 034 29 “Stochastic evolution equations with Lévy noise”. 2 Supported by the Po...
As a Generalization to [37] where the dimension-free Harnack inequality was established for stochastic porous media equations, this paper presents analogous results for a large class of stochastic evolution equations with general monotone drifts. Some ergodicity, compactness and contractivity properties are established for the associated transition semigroups. Moreover, the exponential converge...
