Folding of set-theoretical solutions of the Yang-Baxter equation

چکیده
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.

On 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, ...
متن کاملNon-unitary set-theoretical solutions to the Quantum Yang-Baxter Equation
We develop a theory of non-unitary set-theoretical solutions to the Quantum Yang-Baxter equation. Our results generalize those obtained by Etingof, Schedler and the author in [ESS]. We remark that some of our constructions are similar to constructions obtained by Lu, Yan and Zhu in [LYZ].
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 کاملIndecomposable set-theoretical solutions to the Quantum Yang-Baxter Equation on a set with prime number of elements
In this paper we show that all indecomposable nondegenerate set-theoretical solutions to the Quantum Yang-Baxter equation on a set of prime order are affine, which allows us to give a complete and very simple classification of such solutions. This result is a natural application of the general theory of set-theoretical solutions to the quantum Yang-Baxter equation, developed in [ESS],[LYZ],[S] ...
متن کاملAn Independent Set of Axioms of MV-Algebras and Solutions of the Set-Theoretical Yang-Baxter Equation
The aim of this paper is to give a new equivalent set of axioms for MV-algebras, and to show that the axioms are independent. In addition to this, we handle Yang–Baxter equation problem. In conclusion, we construct a new set-theoretical solution for the Yang–Baxter equation by using MV-algebras.
