buondi',

Il mini-corso sugli invarianti quantistici continua mercoledi prossimo.

Alcuni di noi ieri hanno chiesto a Francois anche un seminario avanzato "informale" (indipendente dal corso), e lo abbiamo fissato per oggi alle 14.30. Mi scuso per lo scarsissimo preavviso.

SEMINARI DI GEOMETRIA 14:30-16:00, Sala Riunioni (Dip. Matematica) Nilpotent Reshetikhin-Turaev invariants of 3-manifolds Francesco Costantino (IRMA Strasbourg)

Abstract:

(Joint work with Nathan Geer and Bertrand Patureau-Mirand.)

The goal of the talk is to review the construction of non-semisimple surgery invariants of three manifolds in the case of sl_2.

After recalling the axiomatic properties of ADO invariants of links and their extensions to graphs we will outline the construction of the "non semi-simple Reshetikhin-Turaev invariants" through surgery presentations and discuss some of its key points. Attention will be payed on the key differences with the standard case of Reshetikhin-Turaev invariants of closed three-manifolds. In the last part of the talk we will provide examples of topological applications of these invariants and in particular to the study of the Volume Conjecture.
