**Date & Time:** Friday, November 21, 2008, 15:30-16:30.

**Venue:** Ramanujan Hall

**Title:** Integrability of Lie Brackets

**Speaker:** Rui Loja Fernandes, Instituto Superior Técnico

**Abstract:** Lie groupoids and Lie algebroids are geometric objects which
extend the notions of Lie groups and Lie algebras. Sophus Lie's famous Third
Theorem stating that every Lie algebra arises from a Lie group is not valid
in this more general context. In this talk I will discuss this problem and
its solution.
