SEMINARIO DE ÁLGEBRA IMERL

Viernes 22 de septiembre, de 11:15 AM a 12:15 PM, IMERL



Expositor: Alain Bruguières, Universidad de Montpellier

Título: Quantum invariants of 3-manifolds and TQFTs I : construction

Resumen: I will explain how certain types of categories give rise to invariants of 3-manifolds, both closed (scalar invariants) and with boundaries (TQFTs). More precisely, spherical categories give rise to the Turaev-Viro invariants, which are achiral,  and modular categories, to the Reshetikhin-Turaev invariants, which are chiral.  I will also explain how the modularity condition can be relaxed, based on Mickael Lallouche's thesis.
