Remarks on hypersurfaces in
Francesco Antonio Denisi, Antonio Laface
We study the birational geometry of hypersurfaces in projective varieties of the form , where satisfies mild assumptions. Building on recent results of He…
MMP for Enriques pairs and singular Enriques varieties
Francesco Antonio Denisi, Ãngel David RÃos Ortiz, Nikolaos Tsakanikas +1
We introduce and study the class of primitive Enriques varieties, whose smooth members are Enriques manifolds. We provide several examples and we demonstrate that this class is sta…
Birational automorphism groups in families of hyper-Kähler manifolds
Francesco Antonio Denisi, Claudio Onorati, Francesca Rizzo +1
We study the behavior of birational automorphism groups in families of projective hyper-Kähler manifolds.
Deformations of primitive Enriques varieties
Francesco Antonio Denisi, Nikolaos Tsakanikas, Zhixin Xie
We develop the deformation theory of primitive Enriques varieties, which are defined as quasi-étale quotients of primitive symplectic varieties by nonsymplectic group actions. In…
Weighted four-dimensional Fano hypersurfaces of K3 type
Valeria Bertini, Francesco Antonio Denisi, Enrico Fatighenti +1
We study weighted Fano fourfolds of K3 type realized as hypersurfaces in weighted projective spaces. Under the additional assumption that the singular locus has dimension at most o…
Polygons of Newton-Okounkov type on irreducible holomorphic symplectic manifolds
Francesco Antonio Denisi
Let be a projective irreducible holomorphic symplectic manifold. We associate with any big -divisor on a convex polygon of dimensio…
