In this paper we prove the Kazhdan-Lusztig type character formula for irreducible highest weight modules with positive rational highest weights over symmetrizable Kac-Moody Lie algebras. 
Koszul duality of affine Kac-Moody algebras and cyclotomic rational DAHA
We give a proof of the parabolic/singular Koszul duality for the category O of affine Kac-Moody algebras. The main new tool is a relation between moment graphs and finite codimensional affine
The Combinatorics of Category O for Symmetrizable Kac-moody Algebras
We show that the structure of blocks outside the critical hyperplanes of category O over any symmetrizable Kac-Moody algebra depends only on the corresponding integral Weyl group and its action on
Kazhdan–Lusztig conjecture via zastava spaces
Abstract We deduce the Kazhdan–Lusztig conjecture on the multiplicities of simple modules over a simple complex Lie algebra in Verma modules in category 𝒪{\mathcal{O}} from the equivariant geometric
Characters of representations of affine Kac-Moody Lie algebras at the critical level
We present an explicit character formula for the irreducible highest weight representations of the non-twisted affine Kac-Moody Lie algebra at the critical level which are integrable over the
The Combinatorics of Category O over symmetrizable Kac-Moody Algebras
We show that the structure of a block outside the critical hyperplanes of category O over a symmetrizable Kac-Moody algebra depends only on the corresponding integral Weyl group and its action on the
On the homomorphisms between Parabolic Verma modules over Kac-Moody Algebras.
We consider a more general parabolic category over symmetrizable Kac-Moody algebras. We introduce a Ringel dual between finite truncations of blocks of the parabolic category and a reductive rule of
Twining Character Formula of Kac-Wakimoto Type for Affine Lie Algebras
We prove a formula of Kac-Wakimoto type for the twining characters of irreducible highest weight modules of symmetric, noncritical, integrally dominant highest weights over affine Lie algebras. This
Two-sided BGG resolutions of admissible representations
We prove the conjecture of Frenkel, Kac and Wakimoto on the existence of two-sided BGG resolutions of G-integrable admissible representations of affine Kac-Moody algebras at fractional levels. As an
Enright functors for Kac-Moody superalgebras
A simple generalization of the Enright functor associated with a non-isotropic simple root of Kac-Moody superalgebras is introduced. Two applications for a Kac-Moody superalgebra without isotropic

It is shown that the modular invariant representations of the Virasoro algebra Vir are precisely the "minimal series" of Belavin et al.
