具有渐近发散扭转的波导
Waveguides with asymptotically diverging twisting
摘要:
我们提供了一类无限体积的无界三维域,其相关的Dirichlet Laplacian的谱是纯离散的。该构造是基于考虑具有渐近发散扭转角的管。
英文摘要:
We provide a class of unbounded three-dimensional domains of infinite volume for which the spectrum of the associated Dirichlet Laplacian is purely discrete. The construction is based on considering tubes with asymptotically diverging twisting angle.
