The classification of endo-trivial modules
This paper settles the classification of all endo-trivial modules for a finite p-group, by treating the remaining case of a p-group having maximal elementary abelian subgroups of rank 2. It is shown that the modules constructed by Alperin using relative syzygies provide the complete list of endo-trivial modules in this case.
