Algebra Seminar: Molev -- Generators of affine W-algebras

Alexander Molev (University of Sydney) 

Friday 27 May, 12-1pm, Place: Carslaw 375 

We construct explicit generators of the affine W-algebra of type A 
associated with a nilpotent matrix whose Jordan blocks are of the 
same size. By applying the quantum Miura transformation we recover
the construction of the principal W-algebra of Fateev and Lukyanov (1988).
In the classical limit and the critical level we thus obtain generators of
the respective classical W-algebras.
