New theorems for Hyers-Ulam stability of lienard equation with variable time lags

Abstract

We investigate a modified Lienard equation (LE) with multiple variable time lags and find assumptions for the Hyers-Ulam stability (HUS) and Hyers-Ulam -Rassias stability (HURS) of the modified (LE) considered. We obtain two results on (HUS) and (HURS) of the equation considered where we use Banach's contraction principle (BCP). © 2018 Badih/Ghusayni, Ed. & Pub.
