摘要：

Multimatrix models for which the index set has a group structure and the interaction obeys a 'zero curvature' condition can be deformed related to central extensions of this group. The deformed multimatrix models lead to statistical systems defined on random graphs with a topological action. It is shown, how these topological theories on graphs can be used to weight graphs according to topological conditions.
