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.
