带p-Laplacian算子三点边值问题拟对称正解的存在性
The Existence of Pseudo-Symmetric Positive Solutions for Three-Point Boundary Value Problems with p-Laplacian
【摘要】 研究下面带p拉普拉斯算子三点边值问题{(φp(u′(t)))′+f(t,u(t),u′(t))=0,t∈(0,1) u(0)=αu′(0),u(η)=u(1)三个拟对称正解的存在性,其中α>0,0<η<1,φp(s)=|s|p-2s,通过应用Avery-Peterson不动点定理,我们得到上述边值问题具有拟对称正解的充分条件.
【Abstract】 In this paper,we establish the existence of three pseudo-symmetric positive solutions for the three-point boundary value problem with one-dimensional p-Laplaican {(φp(u′(t)))′+f(t,u(t),u′(t))=0,t∈(0,1) u(0)=αu′(0),u(η)=u(1) where α>0,0<η<1,φp(s)=|s|p-2s.By the fixed point theorem due to Avery and Peterson,we provide sufficient conditions for the existence of pseudo-symmetric positive solutions for the above boundary value problem.
