The school is devoted to braids and their different applications and aspects. This fifth edition of Winter Braids is supported by the Université de Pau, GDR Tresses, GDR singularités and ANR projects ModGroup, SUSI and VasKho. As in previous edition, the school is recognized and supported by French CNRS as école thématique. Besides the main lectures, there will be three half-days devoted to student presentations (not necessarily focused on braids or their generalisations). All talks will be held in English.
