摘要
运用Leray-Schauder不动点定理讨论了三阶常微分方程边值问题{u'''(t)=λa(t)f(u(t)),t∈(0,1)αu'(0)-βu″(0)=0,u(1)=u'(1)=0正解的存在性,其中λ>0是参数,a∈C([0,1],R),f:R+→R连续且f(0)>0,α,β≥0,α+β>0.
The author studied the existence of positive solutions of a class of nonlinear third order ordinary differential equation u?(t) =λa(t)f(u(t)),t∈(0,1)αu′(0) -βu″(0) =0,u(1) =u′(1) =0 whereλ〉0 is a parameter and a∈C([0,1],R),f:R+→R , is continuous and f(0) 〉0 α,β≥0,α+β〉0 .Our approach is based on the Leray -Schauder fixed point theorem .
