Affine Symmetries of Orbit Polytopes
Erik Friese, Frieder Ladisch
An orbit polytope is the convex hull of an orbit under a finite group . We develop a general theory of possible affine symmetry groups of or…
On Clifford theory with Galois action
Frieder Ladisch
Let be a finite group, a normal subgroup of and . Let be a subfield of the complex numbers and assume that t…
The Schur-Clifford subgroup of the Brauer-Clifford group
Frieder Ladisch
We define a Schur-Clifford subgroup of Turull's Brauer-Clifford group, similar to the Schur subgroup of the Brauer group. The Schur-Clifford subgroup contains exactly the equivalen…
Corestriction for algebras with group action
Frieder Ladisch
We define a corestriction map for equivariant Brauer groups in the sense of Fröhlich and Wall, which contain as a special case the Brauer-Clifford groups introduced by Turull. We s…
