Abstract
A vertex operator approach for form factors of Belavin's (Z/nZ)-symmetric model is constructed on the basis of bosonization of vertex operators in the A_n−1⁽¹⁾ model and vertex-face transformation. As simple application for n=2, we obtain expressions for 2m-point form factors related to the σ^z and σ^x operators in the eight-vertex model.

Key words: vertex operator approach; form factors; Belavin's (Z/nZ)-symmetric model; integral formulae.
