摘要
利用锥映射不动点指数定理研究了二阶时滞微分方程的边值问题{y″(x)+f(x,y(x-τ(x)))=0,0≤x≤1y(x)=0,a≤x≤0或1≤x≤b}证明了其正解的存在性.
We use a fixed point index theorem in cones to study the existence of positive solutions for boundary value problems of the second-order delay differential equations y″(x)+ f(x ,y(x-τ(x)))=0 ,0≤ x≤1 , y(x)=0 , a≤ x≤0 or 1≤ x≤ b .
