研究了Dirichlet Laplacian的两项Weyl律中余项在$mathbb{R}^d$的Lipschitz正则子集类中的最优性。特别地,对于热核迹的短时渐近性,我们证明了误差项不能定量地优于第二项的小-o$。
We study the optimality of the remainder term in the two-term Weyl law for the Dirichlet Laplacian within the class of Lipschitz regular subsets of $mathbb{R}^d$. In particular, for the short-time asymptotics of the trace of the heat kernel we prove that the error term cannot be made quantitatively better than little-$o$ of the second term.
