摘要
By employing Krasnoselskii fixed point theorem, we investigate the existence of multiple positive periodic solutions for a class of state-dependent delay functional differential equations with feedback control. The system considered in this paper is more general and incorporates as special cases various problems which have been studied extensively in the literature. Moreover, some easily verifiable sufficient criteria are established.
