Existence of positive solutions of a nonlinear second-order BVP with integral boundary conditions
摘要
Abstract
The existence of positive solutions for a nonlinear second-order ordinary differential equations BVP with integral boundary conditions {u"(t) + f(t,u(t)) = O, t ∈ (0,1),u(0)=∫2 0u(s)g(s)ds, u(1) = 0 is given by using the monotone iterative method.Where g ∈ L1 [0, 1]is.a nonnegeative function,∫1 0(1-s)g(s)ds<l, and f∈C([O,1]×R+,R+).关键词
