Twisted Representations of Algebra of -Difference Operators, Twisted - Algebras and Conformal Blocks

We study certain representations of the quantum toroidal ₁ algebra for = . We construct explicit bosonization of the Fock modules ⁽ⁿ′'ⁿ⁾ᵤ with a nontrivial slope ′/. As a vector space, it is naturally identified with the basic level 1 representation of affine ₙ. We also study twisted -algebras...

description We study certain representations of the quantum toroidal ₁ algebra for = . We construct explicit bosonization of the Fock modules ⁽ⁿ′'ⁿ⁾ᵤ with a nontrivial slope ′/. As a vector space, it is naturally identified with the basic level 1 representation of affine ₙ. We also study twisted -algebras of sn acting on these Fock modules. As an application, we prove the relation on -deformed conformal blocks, which was conjectured in the study of -deformation of isomonodromy/CFT correspondence.
