利用Leggett-Williams不动点定理,得到了无穷区间上二阶多点边值问题{x″(t)+q(t)f(t),x′(t))=0,t∈J+,x(0)=^m-2∑i=1αix(ζi),x^′(∞)=0,3个正解的存在性结果.
By using Leggett-Williams fixed point theorem, we obtain the existence of triple positive solutions for the following singular second order m-point boundary value problems on the infinite interval.{x″(t)+q(t)f(t),x′(t))=0,t∈J+,x(0)=^m-2∑i=1αix(ζi),x^′(∞)=0,3
