Finite W-algebras are certain associative algebras associated to a complex semisimple
Lie algebra g and a nilpotent element e of g.
In the special case e = 0, the W-algebra is
the universal enveloping algebra. On the other hand, the Yangian Y (glN), introduced
by
Drinfeld, is a deformation of the universal enveloping algebra for the polynomial
current Lie algebra glN[x].
In 2004, Brundan and
Kleshchev found various parabolic presentations for the Yangian Y (glN),
which can be used to define certain
algebras called
shifted Yangians. Moreover,
they gave explicitly
a remarkable realization of finite W-algebras as a quotient of shifted Yangians.
The goal of this talk is to explain the above connections and our generalization to
the superalgebra case.
