Abstract |
|
We determine the torsion free rank of the group of endotrivial modules for any finite group of Lie type, in both defining and nondefining characteristic. Equivalently, we classify the maximal rank elementary abelian -subgroups in any finite group of Lie type, for any prime . This classification may be of independent interest. |
