Algebra Seminar

Yangian characters and classical \(W\)-algebras


Friday 10th August, 12:05--12:55pm, Carslaw 175


Alexander Molev (University of Sydney)


Yangian characters and classical \(W\)-algebras


The Yangian characters (or \(q\)-characters) are known to be closely related to the classical \(W\)-algebras and to the centers of the affine vertex algebras at the critical level. We make this relationship more explicit by producing families of generators of the \(W\)-algebras from the characters of the Kirillov--Reshetikhin modules in types \(B\) and \(D\) and of the fundamental modules in type \(C\). The generators of the \(W\)-algebras correspond to the recently constructed elements of the Feigin--Frenkel centers via an affine version of the Harish-Chandra isomorphism.

This is joint work with Evgeny Mukhin.


After the seminar we will take the speaker to lunch.

See the Algebra Seminar web page for information about other seminars in the series.
