$k$ is an algebraically closed field and $F$ a subfield. All algebraic varieties are over $k$. […] In this section we deal with the structure theory of connected solvable linear algebraic groups. $G$ is such a group. [Theorem of Lie-Kolchin] Assume that $G$ is a closed subgroup of $\mathbf{GL}_n$. There is $x\in\mathbf{GL}_n$ such that $xGx^{-1}\subset\mathbf T_n$. As before $\mathbf T_n$ is the group of upper triangular matrices.
