Curlcurl算子与Stokes算子特征值的比较

Comparison results for eigenvalues of curlcurl operator and Stokes operator

Zhibing Zhang

摘要:

本文主要建立了$\curl\curl$算子与Stokes算子的特征值的比较结果。对于三维单连通有界区域,在切边界条件或法向边界条件下,$\curl\curl$算子的$k$阶本征值严格小于Stokes算子的$k$阶本征值.对任意维数的$n\geq2$,Stokes算子的第一特征值严格大于Dirichlet Laplacian算子的第一特征值.对于三维严格凸区域,$\curl\curl$算子在切边界条件或法向边界条件下的第一特征值严格大于NeumannLaplacian算子的第二特征值.

英文摘要:

This paper mainly establishes comparison results for eigenvalues of $\curl\curl$ operator and Stokes operator. For three-dimensional simply connected bounded domains, the $k$-th eigenvalue of $\curl\curl$ operator under tangent boundary condition or normal boundary condition is strictly smaller than the $k$-th eigenvalue of Stokes operator. For any dimension $n\geq2$, the first eigenvalue of Stokes operator is strictly larger than the first eigenvalue of Dirichlet Laplacian. For three-dimensional strictly convex domains, the first eigenvalue of $\curl\curl$ operator under tangent boundary condition or normal boundary condition is strictly larger than the second eigenvalue of Neumann Laplacian.
