this is joint work with will wylie. the goal is to classify, if possible, the homogeneous geometric solitons. here a geometric soliton is the soliton for a geometric flow. the ricci flow is the most prominent example of such a flow, but there are man others where the ricci tensor is replaced with some other tensor that depends in a natural way on the riemannian structure. we will also consider some more general problems showing that our techniques can be used for other geometric problems.
