| contents | In this paper we investigate composition operators on discrete spaces. We establish the classification of underlying graphs of such operators. For one class of such graphs, namely graphs with one cycle, we obtain a characterization of m-isometries. The paper also contains the solution to the Cauchy dual subnormality problem for composition operators on graphs with one cycle. |
