On the Structure of Involutions and Symmetric Spaces of Quasi Dihedral Group

Zahid Raza, Imran, Bijan Davvaz

Let $G=Q{D}_{8k}$ be the quasi-dihedral group of order $8n$ and $\theta$ be an automorphism of $Q{D}_{8k}$ of finite order. The fixed-point set $H$ of $\theta$ is defined as $H_θ=G^θ=\{x\in G \…
