Abstract

We study the asymptotic behavior of nonlinear Volterra difference system $$ x(n+1)=f(n,x(n))+\sum_{s=n_0}^n g(n,s,x(s)),\;x(n_0)=x_0 $$ by using the resolvent matrix $R(n,m)$ of the corresponding linear Volterra system and the comparison principle.

Keywords: asymptotic equivalence, asymptotic equilibrium, nonlinear Volterra difference system, resolvent matrix, comparison principle
