Abstract

We investigate the representation of the solution of discrete linear Volterra difference systems by means of the resolvent matrix and fundamental matrix, respectively, and then study the boundedness of the solutions of discrete Volterra systems by improving the assumptions and the proofs of Medina's results in \cite{m01cma}.

Keywords: asymptotic equivalence, asymptotic equilibrium, discrete Volt\-erra system, resolvent matrix, fundamental matrix
