Abstract
We describe the most general treatment of all anomalies both for chiral and massless Dirac faermions, in two-dimensional gravity. It is shown that for this purpose two regularization dependent parameters are present in the effective action. An analogy to the Schwinger model is displayed corresponding to a specific choice of the second parameter, thus showing that the gravitational model contains anomaly relations having no analogy in the Schwinger model.File in questo prodotto:
