Hobby Mathematician. PhD drop-out for many reasons 15y ago, but actually can't let go of math.

Interested in Riemannian analysis/geometry - doing it my way...

Unpublished theorem of 1996: A complete Riemannian manifold with strict stochasticly positive Ricci curvature is compact and has finite fundamental group.
(Exact formulation and 1 page proof to be written up one day. I still owe this to KD Elworthy)
