摘要
研究奇异边值问题x″+f(t,x)=0,x(0)=x′(1)=0(x′(0)=x(1)=0正解的存在性,给出其解存在的一个充分必要条件.
The present paper deals with the ex1stence of positive solutlon for generalized singular boundary value problems x' + f(t,x) = 0, x(0) = X'(0) = o (x'(0) = x(1) = 0),gives the sufficient and necessary condition of the existence of the solution.
