Twin positive periodic solutions of second order singular differential systems
Keywords
Singular problem, positive periodic solution, fixed point theorem in cones, Leray-Schauder alternativeAbstract
In this paper, we study positive periodic solutions to singular second order differential systems. It is proved that such a problem has at least two positive periodic solutions. The proof relies on a nonlinear alternative of Leray-Schauder type and on Krasnosel'skiĭ fixed point theorem on compression and expansion of cones.Downloads
