(I have a PhD in pure math — specializing in differential geometry — from a top US university, graduated in the past few years.) I've never heard of an online graduate degree in pure math. If I were to discover that there were indeed such a thing, I'd predict that: * it is not in the US * or, it is a masters degree only * at a for-profit institution * and would have low-quality instruction. I'd count it much more likely that graduate-level courses exist online in a not-for-credit capacity. (In the usual places, eg MIT opencourseware)
