具有混合边界条件的线性弹性算子的谱渐近

Spectral asymptotics for linear elasticity with mixed boundary conditions

Genqian Liu

AI总结:

本文指出Capoferri和Mann给出的线性弹性算子两项谱渐近实为前人已知结果,并纠正了相关文献中一般公式与实例计算的错误。

摘要:

在本文中,我们将证明Capoferri和Mann在\cite{CaMa-24}中给出的具有混合边界条件的线性弹性算子的两项谱渐近,本质上是T. Branson、P. Gilkey、B. Ørsted和A. Pierzchalski在\cite{BGOP}中早已熟知的旧结果。此外,我们进一步指出\cite{SaVa-97, CaFrLeVa-23}中所谓的“一般公式”以及\cite{CaMa-24, CaFrLeVa-23}中对若干例子的计算都是错误的。

英文摘要:

In this note, we shall show that the two-term spectral asymptotics for the operator of linear elasticity with mixed boundary conditions which were given by Capoferri and Mann in \cite{CaMa-24} essentially are old well-known results due to T. Branson, P. Gilkey, B. Ørsted and A. Pierzchalski in \cite{BGOP}. In addition, we further point out that the so-called ``general formulae'' in \cite{SaVa-97, CaFrLeVa-23} and the calculations for several examples in \cite{CaMa-24, CaFrLeVa-23} are all wrong.
