Pfaffian-type Sugawara operators
Published 27 Jul 2011 in math.RT, math-ph, and math.MP | (1107.5417v1)
Abstract: We show that the Pfaffian of a generator matrix for the affine Kac--Moody algebra hat o_{2n} is a Segal--Sugawara vector. Together with our earlier construction involving the symmetrizer in the Brauer algebra, this gives a complete set of Segal--Sugawara vectors in type D.
