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…
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…
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…
Finite groups of symplectic birational transformations of IHS manifolds of type
Lisa Marquand, Stevell Muller
We classify finite groups that act faithfully by symplectic birational transformations on an irreducible holomorphic symplectic (IHS) manifold of OG10 type. In particular, if X is…
Classification of Symplectic Birational Involutions of Manifolds of type
Lisa Marquand, Stevell Muller
We give a complete classification of symplectic birational involutions of manifolds of type. We approach this classification with three techniques -- via involutions of the…
