波群迹与势的规律性

On the trace of the wave group and regularity of potentials

Hart F. Smith

摘要:

对于具有紧支集实势$V$的$\mathbb{R}^d$上的波动方程$\partial_t^2-Δ+V$,建立了$V$的Sobolev正则性与波群相对迹的有穷级展开式$t\rightarrow 0$的存在性之间的一个密切关系.

英文摘要:

For the wave equation $\partial_t^2-Δ+V$ on $\mathbb{R}^d$ with compactly supported, real valued potential $V$, we establish a sharp relation between Sobolev regularity of $V$ and the existence of finite order expansions as $t\rightarrow 0$ for the relative trace of the wave group.
