چکیده
We construct infinite-dimensional analogues of finite-dimensional simple modules the nonstandard q-deformed enveloping algebra Uq′(son) defined by Gavrilik and Klimyk, we do same for classical universal U(son). In this paper only consider case when q is not a root unity, q→1 case. Extending work Mazorchuk on son, provide rational matrix coefficients these both use with rationalized formulas to embed respective algebras into skew group shift operators. Casimir elements were given Iorgov, commutative subalgebra Γ⊂Uq′(son) generated corresponding Γ1⊂U(son). The images Γ Γ1 under their embeddings are equal invariant certain actions. facts show that Harish-Chandra

On Gelfand-Zetlin modules over orthogonal Lie algebras
We construct a new family of simple modules over orthogonal complex Lie algebra associated with Gelfand-Zetlin formulae for simple nite dimensional modules and study the corresponding Gelfand-Zetlin subalgebra.
متن کاملGelfand-tsetlin Algebras and Cohomology Rings of Laumon Spaces
Laumon moduli spaces are certain smooth closures of the moduli spaces of maps from the projective line to the flag variety of GLn. We calculate the equvariant cohomology rings of the Laumon moduli spaces in terms of Gelfand-Tsetlin subalgebra of U(gln), and formulate a conjectural answer for the small quantum cohomology rings in terms of certain commutative shift of argument subalgebras of U(gln).
متن کاملWeight bases of Gelfand–Tsetlin type for representations of classical Lie algebras
This paper completes a series devoted to explicit constructions of finitedimensional irreducible representations of the classical Lie algebras. Here the case of odd orthogonal Lie algebras (of type B) is considered (two previous papers dealt with C and D types). A weight basis for each representation of the Lie algebra o(2n + 1) is constructed. The basis vectors are parametrized by Gelfand–Tset...
متن کاملVertices of Gelfand-Tsetlin Polytopes
This paper is a study of the polyhedral geometry of Gelfand–Tsetlin polytopes arising in the representation theory of glnC and algebraic combinatorics. We present a combinatorial characterization of the vertices and a method to calculate the dimension of the lowest-dimensional face containing a given Gelfand–Tsetlin pattern. As an application, we disprove a conjecture of Berenstein and Kirillov...
متن کاملOn the Bernstein-Gelfand-Gelfand resolution for Kac-Moody algebras and quantized enveloping algebras
A Bernstein-Gelfand-Gelfand resolution for arbitrary Kac-Moody algebras and arbitrary subsets of the set of simple roots is proven. Moreover, quantum group analogs of the Bernstein-Gelfand-Gelfand resolution for symmetrizable Kac-Moody algebras are established. For quantized enveloping algebras with fixed deformation parameter q ∈ C \ {0} exactness is proven for all q which are not a root of un...
