Existence of positive solutions for a class of nonlinear second-order Dirichlet problem
摘要
Abstract
In this paper,we study the existence of positive solutions for a class of nonlinear second-order Dirichlet problem {u"-a(t)u + f(t,u) =0,0 <t < 1,u(0) =u(1) =0,where f:[0,1]× [0,∞) → [0,∞) is continuous,a(t):[0,1]→ [0,∞) is continuous.The proof of the main results is based on the fixed-point theorem of cone expansion-compression.关键词
