Maths HEP Lunchtime Seminars: Sigma models on supermanifolds: Integrability and Conformal Invariance

"Superstrings in AdS5 x S5 are naturally described by a sigma model on a certain supercoset G/H. This space is defined by a Z_4 automorphism, and this automorphism turns out to underlie crucial properties of the theory: kappa symmetry, conformal invariance, and (more surprisingly) classical integrability. We review these ideas before showing that a similar construction holds for a wider class of theories defined by Z_n automorphisms. "
