Some new criteria for generalized contraction of differential systems with delays
Main Article Content
Abstract
In this paper, we generalize the concept contraction to generalized contraction of nonlinear differential systems with time-varying delays. Then we present some new sufficient conditions for generalized contraction of the mentioned systems. An example is given to illustrate the obtained results.
