Duality Beyond the First Loop
In this article we give a calculation of the two-loop $\si$-model corrections to the T-duality map in string theory. We use the effective action approach, and analyze two-loop corrections in a specific subtraction scheme. Focusing on backgrounds which have a single Abelian isometry, we find the expl...
