DUALITY FOR THE G r ; s QUANTUM GROUP 1
نویسندگان
چکیده
The two parameter quantum group G r;s is generated by ve elements, four of which form a Hopf subalgebra isomorphic to GL q (2), while the fth generator relates G r;s to GL p;q (2). We construct explicitly the dual algebra of G r;s and show that it is isomorphic to the single parameter deformation of gl(2) gl(1), with the second parameter appearing in the costructure. We also formulate a di erential calculus on G r;s which provides a realisation of the calculus on GL p;q (2). PACS: 02.20Sv, 02.20Qs, 02.20Nq 1 Kyoto University preprint RIMS 1260 (1999).

The two parameter quantum groups $U_{r,s}(mathfrak{g})$ associated to generalized Kac-Moody algebra and their equitable presentation
We construct a family of two parameter quantum grou-\ps $U_{r,s}(mathfrak{g})$ associated with a generalized Kac-Moody algebra corresponding to symmetrizable admissible Borcherds Cartan matrix. We also construct the $textbf{A}$-form $U_{textbf{A}}$ and the classical limit of $U_{r,s}(mathfrak{g})$. Furthermore, we display the equitable presentation for a subalgebra $U_{r...
متن کاملPresenting cyclotomic q-Schur algebras
We give a presentation of cyclotomic q-Schur algebras by generators and defining relations. As an application, we give an algorithm for computing decomposition numbers of cyclotomic q-Schur algebras. § 0. Introduction Let Hn,r be an Ariki-Koike algebra associated to a complex reflection group Sn ⋉ (Z/rZ). A cyclotomic q-Schur algebra Sn,r associated to Hn,r, introduced in [DJM], is defined as a...

The Cuntz algebra carries in a natural way the structure of a module algebra over the quantized universal enveloping algebra Uq(g), and the structure of a co-module algebra over the quantum group Gq associated with Uq(g). These two algebraic structures are dual to each other via the duality between Gq and Uq(g).
متن کاملDuality of $g$-Bessel sequences and some results about RIP $g$-frames
In this paper, first we develop the duality concept for $g$-Bessel sequences and Bessel fusion sequences in Hilbert spaces. We obtain some results about dual, pseudo-dual and approximate dual of frames and fusion frames. We also expand every $g$-Bessel sequence to a frame by summing some elements. We define the restricted isometry property for $g$-frames and generalize some resu...
متن کاملA Strong Coupling Test of S-duality
By studying the partition function of N = 4 topologically twisted supersymmetric Yang-Mills on four-manifolds, we make an exact strong coupling test of the Montonen-Olive strong-weak duality conjecture. Unexpected and exciting links are found with two-dimensional rational conformal field theory. One of the most remarkable known quantum field theories in four dimensions is the N = 4 supersymmetr...
