Abstract
For a geometric theory with dynamical torsion an absolutely conserved quantity can be related to a Noether current for a peculiar field depe ndent off-shell (global) symmetry. Moreover the nonlinear deformed iso (2, 1) symmetry in phase space discovered previously, for which that c onserved quantity is one element of the center, can be reinterpreted a s a current algebra.
