Nekrasov's Partition Function and Refined Donaldson–Thomas Theory: the Rank One Case
Balázs Szendrői Mathematical Institute, University of Oxford, UK
Abstract:
This paper studies geometric engineering, in the simplest possible case of rank one (Abelian) gauge theory on the affine plane and the resolved conifold. We recall the identification between Nekrasov's partition function and a version of refined Donaldson–Thomas theory, and study the relationship between the underlying vector spaces. Using a purity result, we identify the vector space underlying refined Donaldson–Thomas theory on the conifold geometry as the exterior space of the space of polynomial functions on the affine plane, with the (Lefschetz) $\mathrm{SL}(2)$-action on the threefold side being dual to the geometric $\mathrm{SL}(2)$-action on the affine plane. We suggest that the exterior space should be a module for the (explicitly not yet known) cohomological Hall algebra (algebra of BPS states) of the conifold.
