Kuga-Satake construction on families of K3 surfaces of Picard rank 14
Flora Poon
The isometry between the type IV and the type II hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank …

Slopes of Siegel cusp forms and geometry of compactified Kuga varieties
Flora Poon, Riccardo Salvati Manni, Gregory Sankaran
We study the Kodaira dimension of the compactified n-fold Kuga variety over the moduli space of principally polarised abelian g-folds. We construct a suitable compactification, whi…

On two-elementary K3 surfaces with finite automorphism group
Adrian Clingher, Andreas Malmendier, Flora Poon
We study complex algebraic K3 surfaces of Picard ranks 11,12, and 13 of finite automorphism group that admit a Jacobian elliptic fibration with a section of order two. We prove tha…
