研究了非线性特征值问题−Δp u=λm(X)|u|p−2 u inΩ.∂u/∂n=0 on∂Ω,其中p>1.对于∫Ωm(X)<0,我们证明了第一个正本征值λ1存在且简单唯一,因为它是唯一具有正本征函数的本征值。在∫Ωm(X)=0的情况下,我们证明了λ0=0是唯一具有正特征函数的特征值
We study the nonlinear eigenvalue problem −Δ p u=λm(x)|u| p−2 u in Ω. ∂u/∂n=0 on ∂Ω, where p>1. For ∫ Ω m(x)<0, we prove that the first positive eigenvalue λ 1 exists and is simple and unique, in the sense that it is the only eigenvalue with a positive eigenfunction. In the case ∫ Ω m(x)=0, we prove that λ 0 =0 is the only eigenvalue with a positive eigenfunction
