Subject: DDT&G seminar tomorrow in Amsterdam: Marc Kegel


Dear all,



This is a friendly reminder of tomorrow's Dutch Differential Topology and Geometry seminar:



Speaker: Marc Kegel<https://www.mathematik.hu-berlin.de/~kegemarc/>

Title: "The search for exotic knot traces" (abstract below)

Date: Friday 3 November, 14:00-16:30

Location: VU Amsterdam, NU 9-A46



We hope many of you will join us tomorrow!



Alvaro, Federica and Thomas


Abstract
Every knot leaves a trace in the 4-dimensional world. The trace of a knot is the smooth 4-manifold obtained by attaching a 2-handle to the 4-ball along a knot in the 3-sphere. In the first part of the talk, will carefully introduce these notions and discuss a strategy to disprove the smooth 4-dimensional Poincare conjecture by finding knot traces with certain exotic properties. The second part of the talk is devoted to certain methods and results that might be useful to find such exotic knot traces.
