Stability in Modules for Classical Lie Algebras: A Constructive Approach

Author: Georgia Benkart
language: en
Publisher: American Mathematical Soc.
Release Date: 1990
In this work we consider the problem of determining information about representations as the rank grows large, in fact, tends to infinity. Here we show that the set of dominant weights stabilizes as the rank goes to infinity and the multiplicities become polynomials in the rank. In addition, we give effective, easily computable algorithms for determining the set of dominant weights and illustrate how to calculate their multiplicity polynomials.
Yangians and Classical Lie Algebras

Publisher: American Mathematical Soc.
Release Date: 2007
The Yangians and twisted Yangians are remarkable associative algebras taking their origins from the work of St. Petersburg's school of mathematical physics in the 1980s. This book is an introduction to the theory of Yangians and twisted Yangians, with a particular emphasis on the relationship with the classical matrix Lie algebras.
