RT Journal Article T1 Pulse positive periodic solutions for some classes of singular nonlinearities A1 Nieto, Juan J. A1 Uzal Couselo, José Manuel AB For given nonlinear differential equations it may occur that there are no periodic solutions. By introducing impulses at prescribed instants, periodic solutions may appear. We consider some impulsive nonlinear first order differential equations having periodic solutions and extend previous results to a larger class of nonlinearities.
