Corrigendum to "Nonsymplectic automorphisms of prime order on O'Grady's sixfolds"
Annalisa Grossi, Stevell Muller
In this short note we correct the lattice theoretic classification in [Rev. Mat. Iberoam. 38 (2022), no. 4, 1199--1218] of the first named author, including some missing cases and…
Finite order symplectic birational self-maps on Kummer-type manifolds
Yajnaseni Dutta, Dominique Mattei, Stevell Muller +1
A projective hyperkähler manifold of Kummer-type is said to be twisted modular if it is birational to the Albanese fiber of a moduli space of twisted sheaves on an abelian surface.…
Very ample line bundles on weighted projective spaces and weighted blowups
Stevell Muller, Erik Paemurru
We consider line bundles on weighted projective spaces, where is an integer and is the least common multiple of the weights. Such line bundles are ample i…
Automorphisms of Nikulin-type orbifolds
Simon Brandhorst, Grégoire Menet, Stevell Muller
Nikulin-type orbifolds are certain singular 4-dimensional irreducible holomorphic symplectic varieties. We show that the monodromy group of Nikulin-type orbifolds is maximal and cl…
Algebraically trivial automorphisms of irreducible holomorphic symplectic manifolds
Stevell Muller
We extend the lattice-theoretic approach of Brandhorst--Cattaneo to classify algebraically trivial actions on the known IHS manifolds, up to deformation and birational conjugacy. I…
On birational automorphisms of double EPW-cubes
Simone Billi, Stevell Muller, Tomasz Wawak
We give a classification of finite groups of symplectic birational automorphisms on a manifold of K3^[3]-type with stable and stably saturated cohomological action. We describe the…
