Unitary Groups as Stabilizers of Orbits

Erik Friese

We show that a finite unitary group which has orbits spanning the whole space is necessarily the setwise stabilizer of a certain orbit.

Classification of Affine Symmetry Groups of Orbit Polytopes

Erik Friese, Frieder Ladisch

Let $G$ be a finite group acting linearly on a vector space $V$ . We consider the linear symmetry groups $GL (G v)$ of orbits $G v \subseteq V$ , where the \emph{linear sy…
