Solutions to the quantum Yang–Baxter equation having certain Hopf algebras as their reduced FRT construction

چکیده
Suppose that M is a finite-dimensional vector space over a field k and that R : M ⊗M −→M ⊗M is solution to the quantum Yang–Baxter equation(QYBE). The FRT construction [3] is a bialgebra A(R) associated with R in a natural way. There is a quotient of the FRT construction, referred to as the reduced FRT construction and denoted by Ã(R), which seems rather useful in computation [11]. The bialgebra A(R) is Hopf algebra only when M = (0), whereas the bialgebra Ã(R) may very well be a Hopf algebra. ∗Research supported in part by EPSRC †Research supported in part by NSF Grant no.

The dual ( p , q ) - Alexander - Conway Hopf algebras and the as - sociated universal T - matrix
The dually conjugate Hopf algebras Funp,q(R) and Up,q(R) associated with the two-parametric (p, q)-Alexander-Conway solution (R) of the Yang-Baxter equation are studied. Using the Hopf duality construction, the full Hopf structure of the quasitriangular enveloping algebra Up,q(R) is extracted. The universal T matrix for Funp,q(R) is derived. While expressing an arbitrary group element of the qu...

1. Yang-Baxter algebras (YBA), introduced in [1, 2, 3], generalize the wideknown FRT construction [4] in the following sense: to any numerical matrix solution R of the Yang-Baxter equation there is associated a bialgebra containing the FRT one as a sub-bialgebra. Generally, this construction may provide examples of (new) bialgebras and Hopf algebras [5]. In several aspects, there is some simila...
متن کاملN ov 2 00 3 Symmetric Coalgebras
We construct a structure of a ring with local units on a co-Frobenius coalgebra. We study a special class of co-Frobenius coalgebras whose objects we call symmetric coalgebras. We prove that any semiperfect coalgebra can be embedded in a symmetric coalgebra. A dual version of Brauer's equivalence theorem is presented, allowing a characterization of symmetric coalgebras by comparing certain func...
متن کاملColoured Hopf Algebras
Since its introduction (for reviews see e.g. [1]), the parametrized Yang-Baxter equation (YBE) has played a crucial role in nonlinear integrable systems in physics, such as exactly solvable statistical mechanics models and lowdimensional integrable field theories. Its constant form has also appeared in knot theory, where it is connected with braid groups. In addition, the YBE has inspired the d...
متن کاملQuantum Clifford-Hopf Algebras for Even Dimensions
In this paper we study the quantum Clifford-Hopf algebras ̂ CHq(D) for even dimensions D and obtain their intertwiner R−matrices, which are elliptic solutions to the Yang-Baxter equation. In the trigonometric limit of these new algebras we find the possibility to connect with extended supersymmetry. We also analyze the corresponding spin chain hamiltonian, which leads to Suzuki’s generalized XY ...
