The Ultraviolet Problem in Supergravity

Abstract

We review the development of understanding for the problem of ultraviolet divergences in supergravity. This history proceeds from initial constructions of counterterms invariant under the relevant degrees of local supersymmetry, through a deeper understanding of non-renormalisation theorems for the relevant degrees of ``off-shell'' linearly realisable supersymmetry, and on to current understanding of limitations on counterterm eligibility based on the duality symmetries of supergravity theories, as well as of the related structures emerging in superstring theory.
