Interpolation of fat points on K3 and abelian surfaces

Bulletin of the London Mathematical Society, Volume 56, Issue 9, Page 2863-2873, September 2024.
Abstract We prove that any number of general fat points of any multiplicities impose the expected number of conditions on a linear system on a smooth projective surface, in several cases including primitive linear systems on very general K3 and abelian surfaces, “Du Val” linear systems on blowups of P2${\mathbb {P}}^2$ at nine very general points, and ...

I‐surfaces from surfaces with one exceptional unimodal point

Mathematische Nachrichten, Volume 297, Issue 6, Page 2175-2197, June 2024.
Abstract We complement recent work of Gallardo, Pearlstein, Schaffler, and Zhang, showing that the stable surfaces with KX2=1$K_X^2 =1$ and χ(OX)=3$\chi (\mathcal {O}_X) = 3$ they construct are indeed the only ones arising from imposing an exceptional unimodal double point.

K3 surfaces of Kummer type in characteristic two

Bulletin of the London Mathematical Society, Volume 56, Issue 6, Page 1903-1919, June 2024.
Abstract We discuss K3 surfaces in characteristic two that contain the Kummer configuration of smooth rational curves.
