Non compact (2+1)-TQFTs from spherical non semisimple categories (Nathan Geer)

Séminaire « Topologie »
M3 - Salle des Séminaires

Orateur :  Nathan Geer (Utah State University)

Lieu : salle des Séminaires M3

Résumé : 

To every spherical tensor category (in the sense of Etingof, Douglas et al.) we define a finite dimensional non-compact (2+1)-TQFT. The TQFT of closed surfaces are the admissible skein modules given and the underlying invariants of closed 3-manifolds of the TQFT are the generalized (non-semisimple) Turaev-Viro type invariants.
