Generalized Nikulin surfaces and irreducible symplectic fourfolds

Chiara Camere, Alice Garbagnati, Grzegorz Kapustka +1

A Nikulin surface is the minimal resolution of the quotient of a surface by a symplectic involution . Equivalently, it is the -dimensional component of the fixed l…

A symplectic fourfold

Maria Donten-Bury, Grzegorz Kapustka, Benedetta Piroddi +1

We present a method to construct irreducible symplectic varieties by studying terminalisations of quotient of hyper-Kähler manifolds by non-natural group actions. In particular, we…

Variety of apolar schemes to powers of quadrics

Grzegorz Kapustka, Michał Kapustka, Kristian Ranestad

We study the variety (resp. ), a Grassmannian compactification of the variety of finite schemes of length apolar to …

Even nodal surfaces of K3 type

Marcello Bernardara, Enrico Fatighenti, Grzegorz Kapustka +4

We study Fano fourfolds of K3 type with a conic bundle structure. We construct direct geometrical links between these fourfolds and hyperKähler varieties. As a result we describe f…

Constructions of derived equivalent hyper-Kähler fourfolds

Grzegorz Kapustka, Michał Kapustka

We study twisted derived equivalences of hyper-Kähler fourfolds. We describe when two hyper-Kähler fourfolds of -type of Picard rank with isomorphic transcendental la…

EPW sextics vs EPW cubes

Grzegorz Kapustka, Michal Kapustka, Giovanni Mongardi

We study a correspondence between double EPW cubes and double EPW sextics, two families of polarized hyper-Kähler manifolds related to Gushel--Mukai fourfolds. We infer relations b…
