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…
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…
Quantum Algebras and Cyclic Quiver Varieties
Andrei Neguţ
The purpose of this thesis is to present certain viewpoints on the geometric representation theory of Nakajima cyclic quiver varieties, in relation to the Maulik-Okounkov stable ba…
