Integrable string models with constant torsion in terms of chiral invariants of SU(n), SO(n), SP(n) groups
Abstract
We used the invariant local chiral currents of principal chiral models for SU(n), SO(n), SP(n) groups to construct new integrable string equations of hydrodynamic type on the Riemmann space of the chiral primitive invariant currents and on the chiral non-primitive Casimir operators as Hamiltonians.
