Skew braces were also recently introduced as a tool to study non-dege nerate solutions that are not necessarily involutive. Skew braces appear in many different contexts\, such as near-rings\, matched pairs of groups\, t riply factorized groups\, bijective 1-cocycles\, and Hopf–Galois extensions . In this seminar\, we will give a short introduction to braces and skew br aces\, and we will present a paper by Lindsay Childs which gives a self-con tained proof that a skew left brace yields a solution of the Yang-Baxter eq uation.
