Generalized twisted cubics on a cubic fourfold as a moduli space of stable objects

Martí Lahoz, Manfred Lehn, Emanuele Macrì +1

We revisit the work of Lehn-Lehn-Sorger-van Straten on twisted cubic curves in a cubic fourfold not containing a plane in terms of moduli spaces. We show that the blow-up $Z^{\prime }$ alon…
