NONLINEAR GAUGE-SYMMETRY IN R2-GRAVITY IN 2 DIMENSIONS
The dynamical symmetry of R2-gravity with torsion in two dimensions is investigated within Hamiltonian approach. The symmetry may be interpreted as quadratically deformed iso(2,1)-gauge algebra with the deformation given by the Casimir operators of the undeformed algebra.
