چکیده

We give an introduction to the Fock space representations of the affine Lie algebras ŝln and their quantum analogues Uq(ŝln). We explain the construction of their canonical bases, and the relationship with decomposition matrices of q-Schur algebras at an nth root of 1. In the last section we give a brief survey of some recent higher level analogues of these constructions. Nous donnons une introduction aux représentations de Fock des algèbres de Lie affines ŝln et de leurs analogues quantiques Uq(ŝln). Nous expliquons la construction de leurs bases canoniques, et leur relation avec les matrices de décomposition des q-algèbres de Schur en une racine n-ième de l’unité. Dans la dernière partie nous donnons un bref compte-rendu de résultats analogues récents pour les niveaux supérieurs à 1.

A Littlewood-Richardson rule for evaluation representations of Uq(ŝln)

We give a combinatorial description of the composition factors of the induction product of two evaluation modules of the affine Iwahori-Hecke algebra of type GLm. Using quantum affine Schur-Weyl duality, this yields a combinatorial description of the composition factors of the tensor product of two evaluation modules of the quantum affine algebra Uq(ŝln).

Semi-infinite q-wedge construction of the level 2 Fock Space of Uq ( ˆ sl 2) ∗

In this proceedings a particular example from [KMPY] is presented: the construction of the level 2 Fock space of Uq(ŝl2). The generating ideal of the wedge relations is given and the wedge space defined. Normal ordering of wedges is defined in terms of the energy function. Normally ordered wedges form a base of the wedge space. The q-deformed Fock space is defined as the space of semi-infinite ...

Perfect Crystals and q-deformed Fock Spaces

A b s t r a c t . In [S], [KMS] the semi-infinite wedge construction of level 1 Uq(A (1)) Fock spaces and their decomposition into the tensor product of an irreducible Uq(A(1))-module and a bosonic Fock space were given. Here a general scheme for the wedge construction of q-deformed Fock spaces using the theory of perfect crystals is presented. Let Uq(fJ) be a quantum affine algebra. Let V be a...

Bosonic realizations of Uq(C (1

We construct explicitly the quantum symplectic affine algebra Uq(ŝp2n) using bosonic fields. The Fock space decomposes into irreducible modules of level −1/2, quantizing the Feingold-Frenkel construction for q = 1.

FERMIONIC q-FOCK SPACE AND BRAIDED GEOMETRY

We write the fermionic q-Fock space representation of Uq(ŝln) as an infinite extended braided tensor product of finite-dimensional fermionic Uq(sln)-quantum planes or exterior algebras. Using braided geometrical techniques developed for such quantum exterior algebras, we provide a new approach to the Kashiwara-Miwa-Stern action of the Heisenberg algebra on the q-fermionic Fock space, obtaining ...
