Spectral analysis beyond $\ell^2$ on Sierpinski lattices

Functional Analysis 2021-04-29 v2

Abstract

We study the spectrum of the Laplacian on the Sierpinski lattices. First, we show that the spectrum of the Laplacian, as a subset of C\mathbb{C}, remains the same for any p\ell^p spaces. Second, we characterize all the spectral points for the lattices with a boundary point.
