***************************************************** Winterbraids XI --- first new announcement School on braids and low-dimensional topology Dijon, December 13-17 2021 ******************************************************

Winterbraids XI is the 11th edition of an itinerant school on braids and low-dimensional topology, that will be held at Institut Mathématique de Bourgogne (Dijon) from December 13th to 17th, 2021.

The school consists on four 3-hours mini-courses:

Gwénaël Massuyeau (Université de Bourgogne): Surgery equivalence relations for 3-manifolds. Arunima Ray (Max Planck Institut, Bonn): Slice knots and knot concordance. Gerhard Roehrle (Ruhr-Universität, Bochum): On the K(π,1) problem in hyperplane arrangements. Ramanujan Santharoubane (Université Paris Sud): Applications of quantum representations of mapping class groups.

These will be completed by short talks and a poster session devoted to student presentations (not necessarily focused on braids or their generalizations).

The school will start on Monday morning and will end on Thursday at noon. On the website of the school, there is a pre-registration form, to be filled BEFORE 01/10/2021 . Selected participants will be contacted afterwards to confirm their registration. We will support living expenses for all confirmed registered students and postdocs. The school will be mainly supported by the Conseil Regional Bourgogne Franche-Comté, the Université de Bourgogne, the GDR Tresses and ANR projects AlMaRe.
