关于波导中拉普拉斯算子的共振

On the resonances of the Laplacian on waveguides

Julian Edward

摘要:

本文研究了紧扰动波导中Dirichlet和Neumann Laplacian的共振。上界的物理平面附近的共振的数量被证明。在没有共振的情况下,一个上限证明了本地化的预解式。然后,这是用来证明存在的准模式,其渐近界远离阈值意味着存在的共振收敛到实轴。

英文摘要:

The resonances for the Dirichlet and Neumann Laplacian are studied on compactly perturbed waveguides. An upper bound on the number of resonances near the physical plane is proven. In the absence of resonances, an upper bound is proven for the localised resolvent. This is then used to prove that the existence of a quasimode whose asymptotics is bounded away from the thresholds implies the existence of resonances converging to the real axis.
