Workshop: Towards a Floquet Theory for Periodic Jacobi Matrices on Trees

Speaker
Breuer, The Hebrew University of Jerusalem

Abstract
Periodic Jacobi matrices on the line have a very rich spectral theory, one of whose ingredients is the Floquet theory of eigenfunctions. In this talk we will discuss ongoing work that attempts to generalize this theory to more general trees. We will describe some results obtained in joint works with Jess Banks, Jorge Garza Vargas, Eyal Seelig and Barry Simon.
