Abstract: Assume that G is a finite group and that k is a field of characteristic p. A p-divisible module is one whose absolutely indecomposable direct summands all have dimension divisible by p and whose support variety equals the full spectrum of the cohomology ring. These modules (tensor) generate the stable module category, but not as directly as one would like. There are several interesting problems that involve this class of modules.
