The school, École thématique CNRS, is devoted to braids and their different applications and aspects. This eigth edition of Winter Braids is supported by the Aix-Marseille Université , GDR Tresses, GDR singularités and Foundation Compositio Mathematica. Besides the main lectures, there will be short talks and a poster session devoted to student presentations (not necessarily focused on braids or their generalizations). This edition will be part of a thematic month on low dimensional topology at CIRM. All talks will be held in English. Practical informations are given on "Programme" and "Access" pages.
