On the structure of involutions and symmetric spaces of dihedral groups. (English) Zbl 1336.20025
Summary: We initiate the study of analogues of symmetric spaces for finite groups, with the current work focusing on the family of finite dihedral groups. In particular, we investigate the structure of the automorphism group, characterize the involutions within the automorphism group, and determine the fixed-point subgroup and symmetric space of each automorphism.
