Abstract

We define a new mathematical structure ( graph quantum group) which combines the tower of algebras associated with a graph G and the structure of a Hopf algebra A. In this structure Ocneanu's string operators become Hopf algebra intertwiners. We present some examples of graph quantum groups.
