摘要
We introduce the notion of the action of a group on a labeled graph and the quotient object, also a labeled graph. We define a skew product labeled graph and use it to prove a version of the Gross-Tucker theorem for labeled graphs. We then apply these results to the C*-algebra associated to a labeled graph and provide some applications in non-Abelian duality.
