Multiple positive solutions to superlinear repulsive singular impulsive differential equations
The existence of multiple positive solutions to superlinear repulsive singular impulsive differential equations is discussed in this paper. The proof relies on a nonlinear alternative of Leray-Schauder type and on Krasnoselskii fixed-point theorem on compression and expansion of cone. (c) 2006 Elsevier Ltd. All rights reserved.
