Abstract: | Let k be a field of characteristic different from 2 and 3. In this paper, we study the number of rank-2 k-tori required (in fact exhibit such tori explicitly) for the generation of groups of type A2, G2 and F4 arising from division algebras and subgroups of type D4 of Aut(A), for A an Albert division algebra, over infinite perfect fields. |
