[HTML][HTML] On the transcendental lattices of Hyper-Kähler manifolds

B Piroddi, ÁDR Ortiz - Journal of Pure and Applied Algebra, 2025 - Elsevier
We introduce the notion of a Hyper-Kähler manifold X induced by a Hodge structure of K3-
type. We explore this notion for the known deformation types of Hyper-Kähler manifolds …

On birational transformations of Hilbert schemes of points on K3 surfaces

P Beri, A Cattaneo - Mathematische Zeitschrift, 2022 - Springer
We classify the group of birational automorphisms of Hilbert schemes of points on algebraic
K3 surfaces of Picard rank one. We study whether these automorphisms are symplectic or …

Derived equivalence and Grothendieck ring of varieties: the case of K3 surfaces of degree 12 and abelian varieties

A Ito, M Miura, S Okawa, K Ueda - arXiv preprint arXiv:1612.08497, 2016 - arxiv.org
In this paper, we discuss the problem of whether the difference $[X]-[Y] $ of the classes of a
Fourier--Mukai pair $(X, Y) $ of smooth projective varieties in the Grothendieck ring of …

Constructions of derived equivalent hyper-K\" ahler fourfolds

G Kapustka, M Kapustka - arXiv preprint arXiv:2312.14543, 2023 - arxiv.org
We study twisted derived equivalences of hyper-K\" ahler fourfolds. We describe when two
hyper-K\" ahler fourfolds of $ K3^{[2]} $-type of Picard rank $1 $ with isomorphic …

Derived equivalence and Grothendieck ring of varieties: the case of K3 surfaces of degree 12 and abelian varieties

A Ito, M Miura, S Okawa, K Ueda - Selecta Mathematica, 2020 - Springer
In this paper, we discuss the problem of whether the difference XY XY of the classes of a
Fourier–Mukai pair (X, Y) of smooth projective varieties in the Grothendieck ring of varieties …

Cubic fourfolds with birational Fano varieties of lines

C Brooke, S Frei, L Marquand - arXiv preprint arXiv:2410.22259, 2024 - arxiv.org
We give four examples of pairs of (conjecturally irrational) cubic fourfolds with birationally
equivalent (and in some cases isomorphic) Fano varieties of lines. Two of our examples …

Two polarised K3 surfaces associated to the same cubic fourfold

E Brakkee - … Proceedings of the Cambridge Philosophical Society, 2021 - cambridge.org
For infinitely many d, Hassett showed that special cubic fourfolds of discriminant d are
related to polarised K3 surfaces of degree d via their Hodge structures. For half of the d …

Strongly ambiguous Hilbert squares of projective K3 surfaces with Picard number one

R Zuffetti - arXiv preprint arXiv:1807.06936, 2018 - arxiv.org
We provide a criterion for when Hilbert squares of complex projective K3 surfaces with
Picard number one are strongly ambiguous. This criterion is the same as [DM, Proposition …

On birational transformations and automorphisms of some hyperkähler manifolds

P Beri - 2020 - theses.hal.science
My thesis work focuses on double EPW sextics, a family of hyperkähler manifolds which, in
the general case, are equivalent by deformation to Hilbert's scheme of two points on a K3 …
