Positive solutions for nonlinear first-order periodic boundary value problems of impulsive dynamic equations on time scales

Abstract: In this paper, existence criteria of positive solutions to a class of nonlinear first-order periodic boundary value problems of impulsive dynamic equations on time scales are obtained. The main tool used in this paper is the well-known Guo–Krasnoselskii fixed-point theorem. [Copyright &y& Elsevier]
