Title: Spectral Theory of Graph Laplacians and Orthogonal Polynomials

Abstract: Our main object of interest is the spectrum of the discrete Laplacian on the Cayley graph of the Lamplighter Group. We will show how the spectral theory of orthogonal polynomials is relevant to the determination of this spectrum and present some calculations that provide new examples of spectral phenomena. Based on joint work with R. Grigorchuk.
