Abstract
An open problem given by Kocic and Ladas in 1993 is generalized and considered. A sufficient condition is obtained for each solution to
tend to the positive steady-state solution of the systems of
nonlinear Volterra difference equations of population models with
diffusion and infinite delays by using the method of lower and
upper solutions and monotone iterative techniques.
