周期椭圆型方程解的整表示

Integral representations of solutions of periodic elliptic equations

Peter Kuchment

摘要:

本文讨论了二阶周期椭圆型方程谱下复Fermi面的结构与其某些类解的整表示之间的关系。这些整表示是以前由S. Agmon,S. Helgason和其他作者对于Helmholtz方程的解(即,拉普拉斯算子的广义本征函数)。在以前的工作与Y。Pinchover我们描述了所有的解决方案,可以表示为积分的积极布洛赫解决方案在虚构的费米表面,与超函数作为一个“措施”。在这里,我们的解决方案,使相应的超函数是费米表面上的分布类的特点。

英文摘要:

The paper discusses relations between the structure of the complex Fermi surface below the spectrum of a second order periodic elliptic equation and integral representations of certain classes of its solutions. These integral representations are analogs of those previously obtained by S. Agmon, S. Helgason, and other authors for solutions of the Helmholtz equation (i.e., for generalized eigenfunctions of Laplace operator). In a previous joint work with Y. Pinchover we described all solutions that can be represented as integrals of positive Bloch solutions over the imaginary Fermi surface, with a hyperfunction as a ``measure''. Here we characterize the class of solutions such that the corresponding hyperfunction is a distribution on the Fermi surface.
