Compact moduli of K3 surfaces with a nonsymplectic automorphism
Valery Alexeev, Philip Engel, Changho Han
We construct a modular compactification via stable slc pairs for the moduli spaces of K3 surfaces with a nonsymplectic group of automorphisms under the assumption that some combina…

The flex divisor of a K3 surface
Valery Alexeev, Philip Engel
The flex divisor of a primitively polarized K3 surface of degree is, generically, the locus of all points for which there exists a pencil w…

Compact moduli of K3 surfaces
Valery Alexeev, Philip Engel
We construct geometric compactifications of the moduli space of polarized K3 surfaces, in any degree . Our construction is via KSBA theory, by considering canonical ch…
