Divergent series, Feynman integrals and knot theory

Despite what one might think at first sight, these three topics have much in common. Both the first and last were first seriously studied in the last century in the context of applications to physics, whie Feynman integrals are at once an important tool arising in physics and have been used to "prove" many deep results in mathematics while not currently possessing a rigorous definition.

In this talk, we will demonstrate some of the connections which can be seen between the three topics by investigating the Witten-Reshetikhin-Turaev invariants of knots and 3-manifolds, and will touch on some recent work which demonstrates that there is still much structure in this field yet to be uncovered.

Coffee, Cookies at the faculty lounge at 3:30.

Come to the "after colloquium coffee chat" in Beit-Belgia.
