The Chow of $S^{[n]}$ and the universal subscheme

Andrei Neguţ

We prove that any element in the Chow ring of the Hilbert scheme $Hilb_{n}$ of $n$ points on a smooth surface $S$ is a universal class, i.e. the pushforward of a polynomial in…

Toward AGT for parabolic sheaves

Andrei Neguţ

We construct explicit elements $W_{ij}^{k}$ in (a completion of) the shifted quantum toroidal algebra of type $A$ , and show that these elements act by 0 on the $K$ -theory of moduli s…

The PBW basis of $U_{q, q ˉ} (gl ¨_{n})$

Andrei Neguţ

We consider the PBW basis of the type A quantum toroidal algebra developed by the author, and prove commutation relations between its generators akin to the ones studied by Burban-…
