Quantum integrability of nonultralocal models through Baxterisation of quantised braided algebra
A scheme suitable for describing quantum nonultralocal models including
supersymmetric ones is proposed. Braided algebras are generalised to be used
through Baxterisation for constructing braided quantum Yang--Baxter equations.
Supersymmetric and some known nonultralocal models are derived in the framework
of the present approach. As further applications of this scheme construction of
new quantum integrable nonultralocal models like mKdV and anyonic
supersymmetric models including deformed anyonic super algebra are outlined.Comment: 23 pages (Latex), replaced by extended published versio
Description of D-branes invariant under the Poisson-Lie T-plurality
We write the conditions for open strings with charged endpoints in the
language of gluing matrices. We identify constraints imposed on the gluing
matrices that are essential in this setup and investigate the question of their
invariance under the Poisson-Lie T-plurality transformations. We show that the
chosen set of constraints is equivalent to the statement that the lifts of
D-branes into the Drinfel'd double are right cosets with respect to a maximally
isotropic subgroup and therefore it is invariant under the Poisson-Lie
T-plurality transformations.Comment: 22 pages; added references, the final version accepted for
