Clara Löh: Isomorphisms of Cayley graphs of finitely generated Abelian groups

One of the main objectives of geometric group theory is to understand the relation between algebraic properties of finitely generated groups and (large scale) geometric properties of their Cayley graphs. More rigidly, an important question in combinatorics is to understand how isomorphisms of Cayley graphs are related to the underlying group structure. In this talk I will give a brief introduction into the subject of so-called CI-groups, and I will discuss isomorphisms of Cayley graphs of finitely generated Abelian  groups.
