基于分歧理论的强奇异拟线性问题的多重性

Multiplicity for a strongly singular quasilinear problem via bifurcation theory

Carlos Alberto Santos, Jacques Giacomoni, Lais Santos

摘要:

研究了一类同时具有强奇异和$(p-1)$ -超线性非线性项的$p$ -Laplacian椭圆问题.利用分歧理论、逼近技巧和上下解方法证明了该方程正解的一个无界分支的存在性,该分支在正$λ-$方向上是有界的,并在$λ=0$处从无穷远处分支.由于分歧的结果,我们确定的存在,不存在的区间,并在特定情况下,全球的多重性。

英文摘要:

A $p$-Laplacian elliptic problem in the presence of both strongly singular and $(p-1)$-superlinear nonlinearities is considered. We employ bifurcation theory, approximation techniques and sub-supersolution method to establish the existence of an unbounded branch of positive solutions, which is bounded in positive $λ-$direction and bifurcates from infinity at $λ=0$. As consequence of the bifurcation result, we determine intervals of existence, nonexistence and, in particular cases, global multiplicity.
