· J. Math. Phys. (N.Y.); (United States)
The one loop effective measure for a two-dimensional generalized sigma model with torsion in the presence of an arbitrary gravitational background is computed. The consequences of the result on the relation between the conformal anomalies and the divergences of the model are considered.
