INDECOMPOSABLE DECOMPOSITION OF TENSOR PRODUCTS OF MODULES OVER THE RESTRICTED QUANTUM UNIVERSAL ENVELOPING ALGEBRA ASSOCIATED TO sl2
نویسنده
چکیده
Abstract. In this paper we study the tensor category structure of the module category of the restricted quantum enveloping algebra associated to sl2. Indecomposable decomposition of all tensor products of modules over this algebra is completely determined in explicit formulas. As a by-product, we show that the module category of the restricted quantum enveloping algebra associated to sl2 is not a braided tensor category.

An Embedding of the Universal Askey - Wilson Algebra
The Askey–Wilson algebras were used to interpret the algebraic structure hidden in the Racah–Wigner coefficients of the quantum algebra Uq(sl2). In this paper, we display an injection of a universal analog △q of Askey–Wilson algebras into Uq(sl2) ⊗ Uq(sl2) ⊗ Uq(sl2) behind the application. Moreover we formulate the decomposition rules for 3-fold tensor products of irreducible Verma Uq(sl2)-modu...
متن کاملOn generalized reduced representations of restricted Lie superalgebras in prime characteristic
Let $mathbb{F}$ be an algebraically closed field of prime characteristic $p>2$ and $(g, [p])$ a finite-dimensional restricted Lie superalgebra over $mathbb{F}$. It is showed that anyfinite-dimensional indecomposable $g$-module is a module for a finite-dimensional quotient of the universal enveloping superalgebra of $g$. These quotient superalgebras are called the generalized reduced enveloping ...
متن کاملTHESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Generalized Weyl algebras and elliptic quantum groups
This thesis consists of four papers. In the first paper we present methods and explicit formulas for describing simple weight modules over twisted generalized Weyl algebras. Under certain conditions we obtain a classification of a class of locally finite simple weight modules from simple modules over tensor products of noncommutative tori. As an application we describe simple weight modules ove...
متن کاملQUANTIZED UNIVERSAL ENVELOPING ALGEBRA OF sl2 AND THE ASSOCIATED BRAIDING
In this text we use the quantum double construction to show that a suitable category of finite dimensional left U -modules is braided, where U is the quantized universal enveloping algebra of sl2(k). We produce the expression of the corresponding braiding as the action of a formal universal R-matrix for U . We indicate the generalization to sln(k) and the relation to Hecke algebras and Temperle...

We use tilting modules to study the structure of the tensor product of two simple modules for the algebraic group SL2, in positive characteristic, obtaining a twisted tensor product theorem for its indecomposable direct summands. Various other related results are obtained, and numerous examples are computed. Introduction We study the structure of L ⊗ L where L,L are simple modules for the algeb...
