关于屈曲问题的谱渐近性

On the spectral asymptotics for the buckling problem

Davide Buoso, Paolo Luzzini, Luigi Provenzano, Joachim Stubbe

摘要:

我们提供了一个直接的证明外尔定律的双调和算子的屈曲特征值的$\mathbb R^d$包括有界Lipschitz域的广泛的一类区域。证明依赖于渐近尖锐的下限和上界,我们开发的Riesz平均$R_2(z)$。利用所谓的“平均变分原理“得到了下界。上界的精神Berezin-Li-Yau。此外,我们还对Weyl定律中的第二项提出了一个猜想,并在两种特殊情况下证明了它的正确性:$\mathbb R^d$中的球和$\mathbb R$中的有界区间。

英文摘要:

We provide a direct proof of Weyl's law for the buckling eigenvalues of the biharmonic operator on a wide class of domains of $\mathbb R^d$ including bounded Lipschitz domains. The proof relies on asymptotically sharp lower and upper bounds that we develop for the Riesz mean $R_2(z)$. Lower bounds are obtained by making use of the so-called "averaged variational principle". Upper bounds are obtained in the spirit of Berezin-Li-Yau. Moreover, we state a conjecture for the second term in Weyl's law and prove its correctness in two special cases: balls in $\mathbb R^d$ and bounded intervals in $\mathbb R$.
