Popis: It is shown that the two-point time-dependent temperature correlators of the XXO Heisenberg spin chain satisfy a system of classical equations in the distance between correlating spins and time. This system is an integrable lattice version of the nonlinear Schrodinger equation. Bibliography: 17 titles.
