A finite directed graph gives rise to several objects at once: dynamical systems, inverse semigroups, étale groupoids, and C*-algebras. This talk is an introduction to these constructions and how they classify graphs. We will discuss classical invariants of graphs and how these are realized through topological invariants of groupoids and C*-algebras. We will also discuss how these invariants and other objects classify graphs. No previous familiarity with symbolic dynamics is assumed. The talk also sets up the second part, where these equivalences are revisited from a combinatorial point of view.

We introduce a notion of a graph module which we will use as a unifying framework for the study of the graph algebras and graph groupoids. We will define graph modules and spell out some elementary properties. We will then explain how the Bowen Franks group and the dimension triple can be realized concretely by studying the category of modules over a graph. After this we will generalize this to bimodules and construct a bicategory of graphs and show how this is the category of flow equivalence of graphs. We will give examples and discuss their connection with wrong way maps between graph algebras.

Borrowing W. Paravicini’s linking Banach algebra framework, based on V. Lafforgue’s definition of Morita equivalence for Banach algebras, in this talk we present different ways of putting norms on the linking algebra associated to a Banach Morita equivalence. For equivalences arising from L^p-modules, we show that there is a canonical choice of norm that recovers the usual C*-algebraic setting when p=2. If time permits, I will discuss applications of this result to L^p-operator algebras associated with étale groupoids. This is based on joint work with Yeong Chyuan Chung (Jilin University) and Zhen Wang (HangZhou Normal University).
