On Set-theoretical Solutions of the Quantum Yang-baxter Equation
In the paper [Dr] V.Drinfeld formulated a number of problems in quantum group theory. In particular, he suggested to consider “set-theoretical” solutions of the quantum Yang-Baxter equation, i.e. solutions given by a permutation R of the set X ×X , where X is a fixed set. In this note we study such solutions, which satisfy the unitarity and the crossing symmetry conditions – natural conditions ...
متن کامل“set-theoretical” Solutions of the Quantum Yang-baxter Equation and a Class of Garside Groups
We establish a one-to-one correspondence between structure groups of non-degenerate, involutive and braided “set-theoretical” solutions of the quantum Yang-Baxter equation and Garside groups with a certain presentation. Moreover, we show that the solution is indecomposable if and only if its structure group is a ∆−pure
متن کاملFolding of set-theoretical solutions of the Yang-Baxter equation
We establish a correspondence between the invariant subsets of a non-degenerate symmetric set-theoretical solution of the quantum Yang-Baxter equation and the parabolic subgroups of its structure group, equipped with its canonical Garside structure. Moreover, we introduce the notion of a foldable solution, which extends the one of a decomposable solution. AMS Subject Classification: 16T25, 20F36.

متن کاملOn the Set-theoretical Yang-baxter Equation
Because of this, a solution of (1) gives rise to a linear representation of the braid group Bn on V⊗n for every n. In [D], Drinfel’d raised the question of finding set-theoretical solutions of the YangBaxter equation. Specifically, we consider a set S and an invertible map R : S×S → S×S. We think of the Yang-Baxter equation (1) as an equality of maps from S×S×S to S×S×S. As in the linear case, ...
