L-equivalence and Fourier--Mukai partners of cubic fourfolds
Reinder Meinsma, Riccardo Moschetti
We study L-equivalence in the Grothendieck ring of varieties and its interaction with categorical invariants of cubic fourfolds. Assuming a Derived Torelli-type criterion for Kuzne…

Conic linear series and pencils of plane quartics
Riccardo Moschetti, Gian Pietro Pirola, Lidia Stoppino
We study linear systems cut out by cones of fixed degree on a smooth complex curve . We develop a systematic study of the families of such systems, consider…

Pencils of plane cubics with one base point
Riccardo Moschetti, Gian Pietro Pirola, Lidia Stoppino
We study pencils of plane cubics with only one base point and general member smooth, giving a complete classification. Under the additional hypothesis that all members are irreduci…
