渐近双曲流形的散射极点

Scattering poles for asymptotically hyperbolic manifolds

David Borthwick, Peter Perry

摘要:

对于一类包含实双曲空间的凸余紧离散群的投影的流形,我们证明了Laplacian算子的亚纯连续预解核的共振与亚纯连续散射算子的极点重合,并具有重数.为了进行证明,我们使用Shmuel Agmon的扰动理论的共振,以显示这两个预解共振和散射极点是简单的一般潜在的扰动。

英文摘要:

For a class of manifolds that includes quotients of real hyperbolic space by a convex co-compact discrete group, we show that the resonances of the meromorphically continued resolvent kernel for the Laplacian coincide, with multiplicities, with the poles of the meromorphically continued scattering operator. In order to carry out the proof, we use Shmuel Agmon's perturbation theory of resonances to show that both resolvent resonances and scattering poles are simple for generic potential perturbations.
