Explicit generators in rectangular affine W-algebras of type A (1403.1017v3)
Published 5 Mar 2014 in math.RT, math-ph, and math.MP
Abstract: We produce in an explicit form free generators of the affine W-algebra of type A associated with a nilpotent matrix whose Jordan blocks are of the same size. This includes the principal nilpotent case and we thus recover the quantum Miura transformation of Fateev and Lukyanov.
