变域上多调和算子的特征值

Eigenvalues of poly-harmonic operators on variable domains

Davide Buoso, Pier Domenico Lamberti

摘要:

考虑一类多调和算子的特征值问题,包括Dirichlet型和buckling型本征值问题。我们证明了解析结果的依赖对称函数的特征值域扰动和计算阿达玛型公式的Frechét微分。我们还考虑等容域扰动和特征值的对称函数的相应的临界域。最后,我们证明了球是临界域。

英文摘要:

We consider a class of eigenvalue problems for poly-harmonic operators, including Dirichlet and buckling-type eigenvalue problems. We prove an analyticity result for the dependence of the symmetric functions of the eigenvalues upon domain perturbations and compute Hadamard-type formulas for the Frechét differentials. We also consider isovolumetric domain perturbations and characterize the corresponding critical domains for the symmetric functions of the eigenvalues. Finally, we prove that balls are critical domains.
