The universal sheaf as an operator
Andrei Neguţ
We compute the universal sheaf of moduli spaces M of sheaves on a surface S, as an operator {Symmetric Polynomials} K(M), thus generalizing the viewpoint of Carlsson-…
The Chow of and the universal subscheme
Andrei Neguţ
We prove that any element in the Chow ring of the Hilbert scheme of points on a smooth surface is a universal class, i.e. the pushforward of a polynomial in…
Toward AGT for parabolic sheaves
Andrei Neguţ
We construct explicit elements in (a completion of) the shifted quantum toroidal algebra of type , and show that these elements act by 0 on the -theory of moduli s…
Affine Laumon spaces and a conjecture of Kuznetsov
Andrei Neguţ
We prove a conjecture of Kuznetsov stating that the equivariant K-theory of affine Laumon spaces is the universal Verma module for the quantum affine algebra U_q(gl_n^). We do so b…
