“…In recent years the general problem of proving conditions which assure (1.8), i.e., the problem of boundedness of the solution of a VDE, has been investigated by numerical analysts in many papers (see e.g [4,7,10,11,13,19]). Their increasing interest in this topic is due to the fact that difference equations of the type (1.1) arise from the application of numerical methods to Volterra integral equations (VIEs) and integro-differential equations (VIDEs).…”

“…Their work heavily depended on showing or assuming the summability of the resolvent matrix. For more results on stability of the zero solution of Volterra discrete system we refer the reader to Crisci, Komanovskii and Vecchio [2], Elaydi [3] and Agarwal and Pang [1]. This research is a continuation of the research initiated by the authors in [6] and related to the work in [5].…”
“…Most of the known results for the nonconvolution case are based on the hypothesis of double summability of the coefficients (∑ +∞ =0 ∑ =0 | , | < +∞); see [1,4,[13][14][15][16][17][18][19]. Another interesting approach, resembling the study of continuous VIDE (see, e.g., [20,21]), basically requires that the coefficient +1 of (5), assumed to be negative, in some sense "prevails" on the summation of the remaining coefficients . Here we would like to add another piece to the framework regarding the analysis of VDE behaviour, by considering hypotheses based on the sign of the coefficients and of their first and second differences.…”

We consider homogeneous linear Volterra Discrete Equations and we study the asymptotic behaviour of their solutions under hypothesis on the sign of the coefficients and of the first-and second-order differences. The results are then used to analyse the numerical stability of some classes of Volterra integrodifferential equations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
