Fourier-Mukai partners of non-syzygetic cubic fourfolds and Gale duality
Christian Böhning, Hans-Christian Graf von Bothmer, Lisa Marquand
We study so-called non-syzygetic cubic fourfolds, i.e., smooth cubic fourfolds containing two cubic surface scrolls in distinct hyperplanes with intersection number between the two…
Equivariant birational geometry of cubic fourfolds and derived categories
Christian Böhning, Hans-Christian Graf von Bothmer, Yuri Tschinkel
We study equivariant birationality from the perspective of derived categories. We produce examples of nonlinearizable but stably linearizable actions of finite groups on smooth cub…
On stable cohomology of central extensions of elementary abelian groups
Fedor Bogomolov, Christian Böhning, Alena Pirutka
We study when kernels of inflation maps associated to extraspecial p-groups in stable group cohomology are generated by their degree two components. This turns out to be true if th…
On the dynamical degrees of reflections on cubic fourfolds
Christian Böhning, Hans-Christian Graf von Bothmer, Pawel Sosna
We compute the dynamical degrees of certain compositions of reflections in points on a smooth cubic fourfold. Our interest in these computations stems from the irrationality proble…
