利用不动点指数理论研究了超线性半正奇异三点边值问题un+f(u(t))+q(t)=0,u(0)=0,u(1)=βu(η)0〈t〈1,正解的存在性。其中f:C(0,1)×[0,+∞)→[0,+∞)连续,f在t=0,1处奇异。
We study the existence of positive solutions of superlinear semipositone singular three boundary value problems.Also,we get the corresponding theorem based on the fixed-point theorem of cone.
