Positive solutions to m-point boundary value problems of second order impulsive differential equations
摘要
Abstract
By using the Leggett-williams fixed point theorem, this paper studies the existence of positive solutions to m-point boundary value problems of the second order impulsive differential equations. In some conditions, it shows that the above problem has at least three positive solutions u1 ,u2 and u3 so that || u1 || <Cd,a<la(u2) and || u3 || ≥d, a(u3)≤a.关键词
