Abstract

In this chapter, we determine the orbits of the fixed-point group on the unipotent elements in the generalized symmetric space for each involution of \({\mathrm{SL}}_2(\mathbb {F}_q)\) with \({\mathrm{char}}\left (\mathbb {F}_q \right ) \neq 2\). We discuss how the generalized symmetric spaces can be decomposed into semisimple elements and unipotent elements, and why this decomposition allows the orbits of the fixed-point group on the entire generalized symmetric space to be more easily classified. We conclude by providing a description of and a count for the orbits of the fixed-point group on the unipotent elements in the generalized symmetric space for each involution of \({\mathrm{SL}}_2(\mathbb {F}_q)\).
