Resumen de Endotrivial modules for the sporadic simple groups and their covers

Caroline Lassueur, Nadia Mazza

• In a step towards the classification of endotrivial modules for quasi-simple groups, we investigate endotrivial modules for the sporadic simple groups and their covers. A main outcome of our study is the existence of torsion endotrivial modules with dimension greater than 1 for several sporadic groups with p-rank greater than 1.
