关于周期波导中Neumann Laplacian谱的注记

A note on the spectrum of the Neumann Laplacian in periodic waveguides

Alessandra A. Verri, Carlos R. Mamani

摘要:

我们研究了限制在周期性波导中的Neumann Laplacian $-Δ^N$。在这种情况下,其光谱$σ(-Δ^N)$呈现能带结构。我们的目标和策略是从分析这些波段的渐近行为中获得光谱信息,前提是波导足够薄。

英文摘要:

We study the Neumann Laplacian $-Δ^N$ restricted to a periodic waveguide. In this situation its spectrum $σ(-Δ^N)$ presents a band structure. Our goal and strategy is to get spectral information from an analysis of the asymptotic behavior of these bands provided that the waveguide is sufficiently thin.
