Chaire de la Vallée Poussin 2015

1-5 June 2015
Institut de Recherche en Mathematique et Physique
Université catholique de Louvain,
Belgium



Since its creation in 2001, the Chaire de la Vallée Poussin is entrusted annually to a mathematical prominent figure.
It was held in the past by Jacques Tits, Perci Diaconis, Yakov Eliashberg, Etienne Ghys, Robbert Dijkgraaf, Ross Street, among other renowned mathematicians.

The Chaire de la Vallée Poussin consists in five one-hour lectures to be held during one week at the Université catholique de Louvain in Louvain-la-Neuve, Belgium. The inaugural lecture is expected to be at a colloquium level and accessible to all PhD students in mathematics. The remaining lectures are usually independent among themselves.

Dror Bar-Natan (U. Toronto): Expansions

It is less well known than it should be, that the standard notion of an expansion of a smooth function on a Euclidean space into a power series ("the Taylor expansion") is vastly more general than if first seems; in fact, it is almost ridiculously more general. In my series of talks I will concentrate on expansions for knotted objects in 3 and 4 dimensions, on how these expansions relate these objects to problems in Lie theory, and on how these expansions may be constructed using tools from quantum field theory (which in themselves are "expansions").
