Motivic and cohomological stabilisation of the Quot scheme of points

Michele Graffeo, Sergej Monavari, Riccardo Moschetti +1

We prove that the motive of the punctual Quot scheme $Quot^{d} (O_{A^{n}}^{\oplus r})_{0}$ stabilises, when $n \to \infty$ , to $[\mathrm{Gr}(d-1,\infty)]\cdot \s…

Enriques surfaces with non-generic non-degeneracy

Riccardo Moschetti, Franco Rota, Luca Schaffler

We study the non-degeneracy invariant $nd (Y)$ of complex Enriques surfaces in families. Our first main result shows that $nd (Y)$ cannot increase under specializat…

The motive of the Hilbert scheme of points in all dimensions

Michele Graffeo, Sergej Monavari, Riccardo Moschetti +1

We prove a closed formula for the generating function $Z_{d} (t)$ of the motives $[Hilb^{d} (A^{n})_{0}] \in K_{0} (Var_{C})$ of punctual Hilbert schem…
