摘要/Abstract

摘要：

The existence of at least two positive solutions is presented for the singular second-order boundary value problem

{(p(t)/1 (p(t)x’(t))′+Φ(t)f(t, x(t), p(t)x′(t))=0, 0 ＜t ＜1,

limt→0 p(t)x′(t)=0, x(1)=0.
by using the fixed point index, where f may be singular at x=0 and px’=0.

关键词: Boundary value problems, singularity, fixed point index
