Perturbative quantum (in)equivalence of dual σ models in 2 dimensions
Abstract
Various examples of target space duality transformations are investigated up to two loop order in perturbation theory. Our results show that when using the tree level ('naive') transformation rules the dual theories are in general inequivalent at two loops to the original ones (both for the Abelian and the non Abelian duality).
