Uniqueness Theorem of Constraints for Simple Singularities
Abstract
In a recent paper, Bakalov and Milanov (Compositio. Math. 149: 840888, 2013) proved that the total descendant potential of a simple singularity satisfies the constraints, which come from the algebra of the lattice vertex algebra associated with the root lattice of this singularity and a twisted module of the vertex algebra. In the present paper, we prove that the solution of these constraints is unique up to a constant factor, as conjectured by Bakalov and Milanov in their paper.
