This is the tenth edition of an international school on low dimensional topology, with a particular emphasis on the multiple aspects of braid groups (algebraic, geometrical, topological or algorithmic).
Previous editions: Pau 2010, Caen 2011, Grenoble 2012, Dijon 2014, Pau 2015, Lille 2016, Caen 2017, CIRM 2018, Reims 2019.
Since 2014 Winterbraids proceedings are published on cedram (http:/www.cedram.org/) and referred on mathscinet.
A webpage of the conference is also available at: http://winterbraids.math.cnrs.fr
