Q.4, S, T -- esp. T.3), and in the book Pseudo-reductive Groups (2nd ed.) read all Examples in Chapter 1 as well as Example A.3.8, section A.6, the discussion immediately after the statement of Proposition A.5.9, Example A.8.3, Remark A.8.16, Example B.2.3 (contrast with tori), and Example B.2.9. | |
