Abstract
We present some general results on the classification of endotrivial modules, i.e. the description of the group of endotrivial modules of a finite group. We then discuss the rationality question of lifting endotrivial modules. In this chapter, we use traditional methods in modular representation theory, such as the theory of vertices, sources of modules and the Green’s correspondence.
