Seminar Functional Analysis, Operator Theory and Dynamical Systems - Speaker: Olaf Post (Isospectral magnetic graphs via partitions of numbers).

Ort: Augusteum A - 701

Title: Isospectral magnetic graphs via partitions of numbers. Abstract: In this talk I will present a construction of discrete magnetic non-isomorphic graphs with isospectral Laplacians. The construction is based on gluing building blocks according to a partition of a natural number. The simplest example is $2+2=1+3$ leading to two non-isomorphic graphs. This is joint work with John Fabila-Carrasco and Fernando Lledó. This is a joint seminar of the section Functional Analysis and the group of Matthias Keller at Potsdam University. This talk is held at Potsdam University and broadcasted via Zoom.
