In recent papers, a discrete matrix delayed exponential for a single delay was defined and
its main property connected with the solution of linear discrete systems with a single delay …

In this paper, our main purpose is to study a class of higher-order fractional stochastic delay
differential equations (FSDDEs). We first define a more generalized delay Grammian matrix …

This paper addresses convergence of iterative learning control for impulsive linear discrete
delay systems with randomly varying trial lengths when coefficient matrices of systems are …

In this paper, firstly, a new discrete delayed Mittag–Leffler matrix function is introduced,
which generalizes the existing discrete delayed exponential matrix function. Secondly …

A strong inspiration for studying Sobolev-type fractional evolution equations comes from the
fact that have been verified to be useful tools in the modeling of many physical processes …

In recent results on representation of the solutions of systems of delayed differential
equations, the condition that the linear parts are given by pairwise permutable matrices was …
