Hyper-kähler manifolds

O Debarre - Milan Journal of Mathematics, 2022 - Springer
The aim of this introductory survey is to acquaint the reader with important objects in
complex algebraic geometry: K3 surfaces and their higher-dimensional analogs, hyper …

Classification of automorphisms on a deformation family of hyper-Kähler four-folds by -elementary lattices

S Boissière, C Camere, A Sarti - 2016 - projecteuclid.org
We give a classification of all nonsymplectic automorphisms of prime order p acting on
irreducible holomorphic symplectic four-folds deformation equivalent to the Hilbert scheme …

On the period map for polarized hyperkähler fourfolds

O Debarre, E Macrì - International Mathematics Research …, 2019 - academic.oup.com
We study smooth projective hyperkähler fourfolds that are deformations of Hilbert squares of
K3 surfaces and are equipped with a polarization of fixed degree and divisibility. They are …

Logarithmic Enriques varieties

S Boissiere, C Camere, A Sarti - arXiv preprint arXiv:2409.09160, 2024 - arxiv.org
We introduce logarithmic Enriques varieties as a singular analogue of Enriques manifolds,
generalizing the notion of log-Enriques surfaces introduced by Zhang. We focus then on the …

Verra four-folds, twisted sheaves, and the last involution

C Camere, G Kapustka, M Kapustka… - International …, 2019 - academic.oup.com
We study the geometry of some moduli spaces of twisted sheaves on K3 surfaces. In
particular we introduce induced automorphisms from a K3 surface on moduli spaces of …

Prime order isometries of unimodular lattices and automorphisms of ihs manifolds

S Brandhorst, A Cattaneo - International Mathematics Research …, 2023 - academic.oup.com
We characterize conjugacy classes of isometries of odd prime order in unimodular-lattices.
This is applied to give a complete classification of odd prime order non-symplectic …

Hyper‐Kähler fourfolds and Kummer surfaces

A Iliev, G Kapustka, M Kapustka… - Proceedings of the …, 2017 - Wiley Online Library
We show that a Hilbert scheme of conics on a Fano fourfold double cover of P 2× P 2
ramified along a divisor of bidegree (2, 2) admits a P 1‐fibration with base being a hyper …

Non-symplectic automorphisms of odd prime order on manifolds of K 3 n-type

C Camere, A Cattaneo - manuscripta mathematica, 2020 - Springer
We contribute to the classification of non-symplectic automorphisms of odd prime order on
irreducible holomorphic symplectic manifolds which are deformations of Hilbert schemes of …

[HTML][HTML] Complex ball quotients from manifolds of K3 [n]-type

S Boissière, C Camere, A Sarti - Journal of Pure and Applied Algebra, 2019 - Elsevier
We describe periods of irreducible holomorphic symplectic manifolds of K 3 [n]-type with a
non-symplectic automorphism of prime order p≥ 3. These turn out to lie on complex ball …
