In this paper, the authors study the existence of positive solution of the following BVP {1/p(t)(P(t)x′)′+f(t,x(t),p(t)x′(t))=0,o〈t〈+∞ αx(0)-βlimt→0p(t)x′(t)=0,γ limt→+∞x(t)+δl...In this paper, the authors study the existence of positive solution of the following BVP {1/p(t)(P(t)x′)′+f(t,x(t),p(t)x′(t))=0,o〈t〈+∞ αx(0)-βlimt→0p(t)x′(t)=0,γ limt→+∞x(t)+δlimt→+∞p(t)x′(t)=0 on the semi-infinite interval. By considering characterization of the nonlinearity, they obtain some new existence results.展开更多
