Highlights in Linear Algebraic Groups 14: Singular Tori

From Highlights 12 and Highlights 13, we have gained quite a bit of information on connected reductive groups $G$ of semisimple rank 1. Recall, this means that $G/R(G)$ has rank 1 where $R(G)$ is the radical of $G$, which is in turn the connected component of the unique maximal normal solvable […]
