Title: Kac-Wakimoto hierarchies and W-symmetries
Date: Tue, Aug 05, 2014, 13:30 - 15:00
Place: Seminar Room A
Abstract: We investigate the Kac-Wakimoto hierarchies using the language of vertex algebras. One application is the proof of Virasoro symmetries of these hierarchies. For the case of types sl(N) and so(2N), we realize the Kac-Wakimoto hierarchies as reductions of the N-component KP and DKP hierarchies, respectively. In these cases, we prove that the corresponding W-algebras act as symmetries.
