Recent Results on N=2 Superconfomal Algebras

Beatriz Gato-Rivera

(I.MA.F.F.-C.S.I.C.)

I will present recent results on N=2 superconfomal algebras, focusing mostly (although not exclusively) on the topological N=2 algebra. The topics will include: i) The exsitence of the odd spectral flow which is much more interesting than the usual (even) spectral flow and which is, in addition, its generator. ii) the chral determinant formulae and iii) some properties of the singular and subsingular vectors. The results I will present have been obtained partially in collaboration with J.I. Rosado, partially in collaboration with M. Doerrzapf and partially by myself.

The almuerzo-seminario is intended to be an informal seminar and an open forum for discussion.

You are wellcome to bring your own bocata (sandwich), or coffee or tea.
