弯曲波导中线性算子束本征值的存在性--弯曲海岸上的局部陆架波

Existence of eigenvalues of a linear operator pencil in a curved waveguide -- localized shelf waves on a curved coast

E R Johnson, Michael Levitin, Leonid Parnovski

摘要:

研究弯曲海岸上存在非传播的、被捕获的大陆架波(CSW)的可能性,在数学上归结为一个弯曲带中自伴算子束的谱问题。使用的方法中开发的设置的波导捕获模式的问题,我们表明,这样的CSWs存在广泛的一类海岸曲率和深度剖面。

英文摘要:

The study of the possibility of existence of the non-propagating, trapped continental shelf waves (CSWs)along curved coasts reduces mathematically to a spectral problem for a self-adjoint operator pencil in a curved strip. Using the methods developed in the setting of the waveguide trapped mode problem, we show that such CSWs exist for a wide class of coast curvature and depth profiles.
