Vertex-algebraic structure of principal subspaces of standard A_2^{(2)}-modules, I

Extending earlier work of the authors, this is the first in a series of papers devoted to the vertex-algebraic structure of principal subspaces of standard modules for twisted affine Kac-Moody

Vertex-algebraic structure of the principal subspaces of certain A_1^(1)-modules, I: level one case

This is the first in a series of papers in which we study vertex-algebraic structure of Feigin-Stoyanovsky's principal subspaces associated to standard modules for both untwisted and twisted affine

Principal subspaces of twisted modules for certain lattice vertex operator algebras

This is the third in a series of papers studying the vertex-algebraic structure of principal subspaces of twisted modules for lattice vertex operator algebras. We focus primarily on lattices

Principal subspaces of basic modules for twisted affine Lie algebras, $q$-series multisums, and Nandi's identities

. We provide an observation relating several known and conjectured q -series identities to the theory of principal subspaces of basic modules for twisted affine Lie algebras. We also state and prove

Combinatorial bases of modules for affine Lie algebra B2(1)

We construct bases of standard (i.e. integrable highest weight) modules L(Λ) for affine Lie algebra of type B2(1) consisting of semi-infinite monomials. The main technical ingredient is a

(k,r)-admissible configurations and intertwining operators

Certain combinatorial bases of Feigin-Stoyanovsky's type subspaces of level k standard modules for affine Lie algebra sl(r,C)\sptilde are parametrized by (k,r)-admissible configurations. In this note

Construction of the affine Lie algebraA1(1)

We give an explicit construction of the affine Lie algebraA1(1) as an algebra of differential operators on ℂ[x1,x3,x5, ...]. This algebra is spanned by the creation and annihilation operators and by

Intertwining vertex operators and certain representations of sl(n)

We study the principal subspaces, introduced by B. Feigin and A. Stoyanovsky, of the level 1 standard modules for $\hat{\goth{sl}(l+1)}$ with $l \geq 2$. In this paper we construct exact sequences

Quasi-particles models for the representations of Lie algebras and geometry of flag manifold

We give a new interpretation and proof of the "quasi-particle" type character formulas for integrable representations of the simply-laced affine Kac-Moody algebras through a new "semi-infinite"

Principal $\hat{sl}(3)$ subspaces and quantum Toda Hamiltonian

We study a class of representations of the Lie algebra of Laurent polynomials with values in the nilpotent subalgebra of sl(3). We derive Weyl-type (bosonic) character formulas for these
