### Partial group algebra with projections and relations

Danilo Royer

#### Abstract

We introduce the notion of the partial group algebra with projections and relations and show that this $C^*$-algebra is a partial crossed product. Examples of partial group algebras with projections and relations are the Cuntz-Krieger algebras and the unitization of $C^*$-algebras of directed graphs.
