Beurling-Fourier algebras of compact quantum groups: characters and finite dimensional representations
نویسندگان
چکیده
In this paper we study weighted versions of Fourier algebras compact quantum groups. We focus on the spectral aspects these Banach in two different ways. first investigate their Gelfand spectrum, which shows a connection to maximal classical closed subgroup and its complexification. Secondly, specific finite dimensional representations coming from complexification underlying group. demonstrate that can detect structure special case $SU_q(2)$, whose is Lorentz group $SL_q(2,\mathbb{C})$.

Spectral Characters of Finite–dimensional Representations of Affine Algebras
In this paper we study the category C of finite–dimensional representations of affine Lie algebras. The irreducible objects of this category were classified and described explicitly in [2],[4]. It was known however that C was not semisimple. In such a case a natural problem is to describe the blocks of the category. The blocks of an abelian category are themselves abelian subcategories, each of...
متن کاملElliptic Central Characters and Blocks of Finite Dimensional Representations of Quantum Affine Algebras
The category of finite dimensional (type 1) representations of a quantum affine algebra Uq(ĝ) is not semisimple. However, as any abelian category with finite-length objects, it admits a unique decomposition in a direct sum of indecomposable subcategories (blocks). We define the elliptic central character of a finite dimensional (type 1) representation of Uq(ĝ) and show that the block decomposit...
متن کاملCharacters and Blocks for Finite–dimensional Representations of Quantum Affine Algebras
In this paper we study the category Cq of finite–dimensional representations of a quantum loop algebraU. Our aim is to study and to put into a common representation theoretic framework, two kinds of characters which have been associated to an object of Cq. One is the notion of q–characters defined in [19] which is analogous in this context, to the usual notion of a character of a finite–dimensi...
متن کاملCOMBINATORICS OF q–CHARACTERS OF FINITE-DIMENSIONAL REPRESENTATIONS OF QUANTUM AFFINE ALGEBRAS
We study finite-dimensional representations of quantum affine algebras using q–characters. We prove the conjectures from [FR2] and derive some of their corollaries. In particular, we prove that the tensor product of fundamental representations is reducible if and only if at least one of the corresponding normalized R–matrices has a pole.
متن کاملt-analogue of the q-characters of finite dimensional representations of quantum affine algebras
Frenkel-Reshetikhin introduced q-characters of finite dimensional representations of quantum affine algebras [6]. We give a combinatorial algorithm to compute them for all simple modules. Our tool is t-analogue of the q-characters, which is similar to Kazhdan-Lusztig polynomials, and our algorithm has a resemblance with their definition. We need the theory of quiver varieties for the definition...
