具变号权函数的p-Laplace方程正径向解的全局分歧结构
Global Bifurcation Structure of Positive Radial Solutions for p-Laplacian Equations with Sign-Changing Weight Function
摘要
Abstract
We investigated the global structure of positive radial solutions for a class of quasilinear elliptic boundary value problems with Dirichlet boundary conditions based on bifurcation theory.Specifically,by introducing two critical exponents f0 and f∞,under two typical cases of f0 ∈(0,∞),f∞=0 and f0=∞,f∞=0,we prove the existence of unbounded connected branches emanating from bifurcation points,which utimately asymptotically extend to infinity along the λ-axis.关键词
