一类奇异非线性Dirichlet问题
A Singular Nonlinear Dirichlet Problem
摘要
Abstract
By constructing the new subsolution and supersolution, and the perturbed method,combining the gstimate argument, we exactly show the parameter β how to affect existence,nonexistence, regularity, and the asymptotic behavior on Ω of the classical solutions to the singular boundary value problem-△u = g(x)u-γ+ λup,u > 0,x ∈Ω,u | Ω = 0, where Ω is a bounded domain with smooth boundary in RN, γ> 0,λ≥ 0, p > 0, g ∈ C loc ( Ω ) and bo ψβ1≤ g ≤ b1 ψβ1 on Ω, β∈ R, bo, b1 are positive constants, φ1 is the normal first eigenfunction.关键词
