Roberto Volpato (MPI Golm): Symmetries of N=(4,4) non-linear sigma models (Simons Lecture on Mathematical Physics)

Roberto Volpato (MPI Golm)


Abstract: Two-dimensional conformal field theories with N=(4,4) superconformal symmetry and central charge 6 arise in compactifications of type II superstrings to six (or less) spacetime dimensions with 16 spacetime supersymmetries. There are two (known) classes of such conformal field theories, namely supersymmetric non-linear sigma models on a K3 surface or on a torus of real dimension four. I will discuss the main properties of these two classes of models and, in particular, the classification of the groups of symmetries that fix the N=(4,4) superconformal algebra.
