Abstract

A review is given of a recently proposed modification of the Abelian Duality transformations guaranteeing that a (not necessarily conformally invariant) a-model be quantum equivalent (at least up to two loops in perturbation theory) to its dual. This requires a somewhat non standard perturbative treatment of the dual sigma-model. Explicit formulaeof the modified duality transformation are presented for a special class of block diagonal purely metric sigma-models.
