The origin of the trace anomaly and of the central charge in the Virasoro algebra associated with the energy-momentum tensor of a bosonic two-dimensional model is considered. It is shown that both these quantities represent different aspects of the same gravitational anomaly.

Abstract
The origin of the trace anomaly and of the central charge in the Virasoro algebra associated with the energy-momentum tensor of a bosonic two-dimensional model is considered. It is shown that both these quantities represent different aspects of the same gravitational anomaly.File in questo prodotto:
