Quantized Universal Enveloping Algebra

Regular An-crystals are certain edge-colored directed graphs, which are related to representations of the quantized universal enveloping algebra Uq(𝔰𝔩n+1). For such a crystal K with colors 1,2,…,n, we consider its maximal connected subcrystals with colors 1,…,n-1 and with colors 2,…,n and characterize the interlacing structure for all pairs of these subcrystals. This enables us to give a recursive description of the combinatorial structure of K via subcrystals and develop an efficient procedure of assembling K.

Quantized Universal Enveloping Algebra

We describe existence conditions and explicitly construct elements for a Heisenberg family in the principal grading of the quantized universal enveloping algebra [Formula: see text] of an affine Kac–Moody algebra [Formula: see text] in the Drinfeld formulation.

Algebra Over A Field

AbstractWe construct an explicit set of algebraically independent generators for the center of the universal enveloping algebra of the centralizer of a nilpotent matrix in the general linear Lie algebra over a field of characteristic zero. In particular, this gives a new proof of the freeness of the center, a result first proved by Panyushev, Premet and Yakimova.
