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...
متن کاملFERMIONIC 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 ...
متن کاملCanonical bases of higher-level q-deformed Fock spaces
We define canonical bases of the higher-level q-deformed Fock space modules of the affine Lie algebra sl n generalizing the result of Leclerc and Thibon for the case of level 1. We express the transition matrices between the canonical bases and the natural bases of the Fock spaces in terms of certain affine Kazhdan-Lusztig polynomials. Leclerc and Thibon defined, in [6], a canonical basis of th...
متن کاملLevel - 0 action of U q ( c sl n ) on the q - deformed Fock spaces
On the level-1 Fock space modules of the algebra U q ( b sl n ) we de ne a level-0 action U 0 of the U 0 q ( b sl n ), and an action of an Abelian algebra of conserved Hamiltonians commuting with the U 0 . An irreducible decomposition of the Fock space with respect to the level-0 action is derived by constructing a base of the Fock space in terms of the Non-symmetric Macdonald Polynomials. 1 e-...
