Andrzej Zuk
Andrzej Zuk (Paris 7) visited Laboratory of Algebraic Geometry in May 2018 at the invitation of Research Fellow Ekaterina Amerik.
On May 21th 2018 Andrzej Zuk gave a talk "PDEs, automata and groups" at the seminar of Laboratory.
Abstract:
We present a construction which associates to the KdV equation the lamplighter group. It uses the L2 Betti numbers introduced by Atiyah which are homotopy invariants of closed manifolds.
