“…As reformulated by Cedó, Jespers, and Okńinski in [13], a left brace is a set B with two operations + and • such that (B, +) is an abelian group, (B, •) is a group and the relation a • (b + c) + a = a • b + a • c holds for all a, b, c ∈ B. Braces have been widely studied, see for instance [30,8,19,31,3,1,11,25]. Soloviev in [33] and Lu, Yan, and Zhu in [26] studied bijective not necessarily involutive solutions.…”
