The centre of quantum sln at a root of unity

چکیده
In [8] de Concini, Kac and Procesi introduced the simply connected quantised universal enveloping algebra U = Uε,P (g) over C at a primitive lth root of unity ε associated to a simple finite-dimensional complex Lie algebra g. The importance of the study of the centre Z of U and its spectrum Maxspec(Z) is pointed out in [7,8]. In this article we consider the following two conjectures concerning the centre Z of U in the case g= sln:

Crystal Bases of Quantum Affine Algebras and Affine Kazhdan-lusztig Polynomials
We present a fast version of the algorithm of Lascoux, Leclerc, and Thibon for the lower global crystal base for the Fock representation of quantum affine sln. We also show that the coefficients of the lower global crystal base coincide with certain affine KazhdanLusztig polynomials. Our algorithm allows fast computation of decomposition numbers for tilting modules for quantum slk at roots of u...
متن کاملFace Algebras and Unitarity of Su(n)l-tqft
Using face algebras (i.e. algebras of L-operators of IRF models), we construct modular tensor categories with positive definite inner product, whose fusion rules and S-matrices are the same as (or slightly different from) those obtained by Uq(slN ) at roots of unity. Also we obtain state-sums of ABF models on framed links which give quantum SU(2)-invariants of corresponding 3-manifolds.
متن کاملthe Degree of Doctor of Philosophy of the University of London Representations at a Root of Unity of q - Oscillators and Quantum Kac - Moody Algebras
The subject of this thesis is quantum groups and quantum algebras at a root of unity. After an introductory chapter, I set up my notation in chapter 2. The rest of the thesis is presented in three parts. In part I, quantum matrix groups and quantum enveloping algebras are discussed. In chapter 3, I present two well-known 2 × 2 matrix quantum groups, including their coaction on the quantum plane...
متن کاملGeometric construction of metaplectic covers of GLn in characteristic zero
This paper presents a new construction of the m-fold metaplectic cover of GLn over an algebraic number field k, where k contains a primitive m-th root of unity. A 2-cocycle on GLn(A) representing this extension is given and the splitting of the cocycle on GLn(k) is found explicitly. The cocycle is smooth at almost all places of k. As a consequence, a formula for the Kubota symbol on SLn is obta...
متن کاملQuantum matrix algebra for the SU(n) WZNW model
The zero modes of the chiral SU(n) WZNW model give rise to an intertwining quantum matrix algebra A generated by an n×n matrix a = (aα) , i, α = 1, . . . , n (with noncommuting entries) and by rational functions of n commuting elements qi satisfying n ∏ i=1 qi = 1, qaα = a j αq pi+δ j i− 1 n . We study a generalization of the Fock space (F) representation of A for generic q (q not a root of uni...
