NONLINEAR ANALYSIS-HYBRID SYSTEMS, cilt.2, sa.2, ss.532-543, 2008 (SCI-Expanded)
In this paper we investigate the existence and stability of the periodic solutions of a quasilinear differential equation with piecewise constant argument. The continuous and differentiable dependence of the solutions on the parameter and the initial value is considered. A new Gronwall-Bellman type lemma is proved. Appropriate examples are constructed.
