• Authors: Anastasia Doikou,
• Abstract summary: The theory of the set-theoretic Yang-Baxter equation is reviewed from a purely algebraic point of view. The notion of braces is also presented as the suitable algebraic structure associated to involutive set-theoretic solutions. The quantum algebra as well as the integrability of Baxterized involutive set-theoretic solutions is also discussed.

• Abstract: The theory of the set-theoretic Yang-Baxter equation is reviewed from a purely algebraic point of view. We recall certain algebraic structures called shelves, racks and quandles. These objects satisfy a self-distributivity condition and lead to solutions of the Yang-Baxter equation. We also recall that non-involutive solutions of the braid equation are obtained from shelf and rack solutions by a suitable parametric twist, whereas all involutive set-theoretic solutions are reduced to the flip map via a parametric twist. The notion of braces is also presented as the suitable algebraic structure associated to involutive set-theoretic solutions. The quantum algebra as well as the integrability of Baxterized involutive set-theoretic solutions is also discussed. The explicit form of the Drinfel'd twist is presented allowing the derivation of general set-theoretic solutions.

We present a systematic and unified treatment for the odd and even sectors of these models.

  We show that analogs of coherent states constructed by the noncommutative integration can be expressed in terms of the solution of a system of differential equations on the Lie group. The solutions constructed are directly related to irreducible representation of the Lie algebra on the Hilbert space functions on the Lagrangian submanifold to the orbit of the coadjoint representation.

  We present a class of deformed creation and annihilation operators that originates from a rigorous notion of fuzziness. This leads to deformed, sub-bosonic commutation relations inducing a simple algebraic structure with modified eigenenergies and Fock states. In addition, we investigate possible consequences of the introduced formalism in quantum field theories, as for instance, deviations from linearity in the dispersion relation for free quasibosons.
