Sara Pasquetti is spending this semester as an Emmy Noether Fellow at the Perimeter Institute in Canada.  On Wednesday 18th March, she gave a colloquium on “Exact results in supersymmetric gauge theories in various dimension“.  One of the central challenges in theoretical physics is to develop non-perturbative methods to describe quantitatively the dynamics of strongly coupled quantum fields. Much progress in this direction has been made for theories with a higher degree of symmetry, such as conformal symmetry or supersymmetry. In recent years the method of localisation has allowed one to obtain numerous exact results for supersymmetric gauge theories in various dimensions and this has led to the discovery of new surprising correspondences such as the celebrated Alday-Gaiotto-Tachikawa correspondence.  The talk will review some recent results which indicate that partition functions of supersymmetric theories formulated on compact manifolds can be expressed in terms of a small set of fundamental building blocks.
