Abstract

We construct local M-operators for an integrable discrete time version of the classical Heisenberg magnet by convolution of the twisted quantum trigonometric 4×\times4 R-matrix with certain vectors in its "quantum" space. Components of the vectors are identified with τ\tau-functions of the model. Hirota's bilinear formalism is extensively used. The construction generalizes the known representation of M-operators in continuous time models in terms of Lax operators and classical rr-matrix.
