证明了当p > 1时,Ω是R中有界区域且边界光滑的p-双调和算子的非线性特征值问题,其主正特征值λ1是简单的孤立的.相应的本征函数在Ω中是正的,并且在Ω中满足<$u <$n < 0,在Ω中满足<$u 1 < 0。我们还证明了(λ1,0)是相关非齐次问题的全局分歧点。在N = 1的情况下,我们给出了所有特征值和相关特征函数的描述。每个这样的特征值都是全局分歧点。
We prove that the nonlinear eigenvalue problem for the p-biharmonic operator with p > 1, and Ω a bounded domain in R with smooth boundary, has principal positive eigenvalue λ1 which is simple and isolated. The corresponding eigenfunction is positive in Ω and satisfies ∂u ∂n < 0 on ∂Ω, ∆u1 < 0 in Ω. We also prove that (λ1, 0) is the point of global bifurcation for associated nonhomogeneous problem. In the case N = 1 we give a description of all eigenvalues and associated eigenfunctions. Every such an eigenvalue is then the point of global bifurcation.
