Symmetries of the classical Heisenberg model

Abstract: The symmetries of the classical Heisenberg model are examined. It is shown that such symmetries are groups of conformal transformations and rotations. The invariance of vortex structures with respect to a group of rotations is studied. The application of the found transformations of the group of field rotations to the already known solutions of the Heisenberg model (such as instantons, vortex “targets” and “spirals”) generates other structures, which are also solutions of this model, with the properties being determined by the original structures.
