摘要:

该文利用Leggett-Williams 不动点定理, 研究半无穷区间边值问题

(p(t)x'(t))'+Φ(t) f (t, x(t), x'(t))=0, t ∈ [0, +∞),
α1x(0)-β1limt →0+ p(t) x'(t)=a1,
α2limt →+∞ x'(t)+β2limt →+∞ p(t) x'(t)=a2

多个正解的存在性.

关键词: 正解, 不动点, 二阶边值问题

Abstract:

In this paper, by using the Leggett-Williams fixed point theorem, the authors discuss the existence of at least three solutions for a class of second order boundary value problems on the half-line as follows 
 

(p(t)x'(t))'+Φ(t) f (t, x(t), x'(t))=0, t ∈ [0, +∞),
α1x(0)-β1limt →0+ p(t) x'(t)=a1,
α2limt →+∞ x'(t)+β2limt →+∞ p(t) x'(t)=a2

Key words: Positive solution, Fixed point, Second order boundary value problem
