Abstract:

This paper studied a kind of nonlinear stochastic difference equations, whose randomness is driven by a stochastic series. Two comparison theorems were obtained. At last, p-moment stability and p-moment boundedness of solutions to stochastic difference equations were presented as applications of obtained comparison theorems.

Key words: comparison theorem, p-moment stability, p-moment boundedness, stochastic difference equation, comparison theorem, p-moment stability, p-moment boundedness
