Holography and the origin of anomalies

The holographic principle is represented as the well-known de Alfaro et al. correspondence between the generating functional for the Green functions of the Euclidean quantum field theory in D dimensions and the Gibbs average for the classical statistical mechanics in (D+1)-dimensions. This correspondence is used to explain the origin of quantum anomalies and the irreversibility in the classical theory. The holographic mapping of a classical string field theory onto a local quantum field theory is outlined.
