Roth’s theorem
I am in Kyoto right now, attending the twentyfirst Nevanlinna colloquium (update: took a while to write this post – now I’m in Sydney for the Clay lectures). Yesterday, Junjiro Noguchi gave a plenary talk on Nevanlinna theory in higher dimensions … Continue reading
Surface subgroups in hyperbolic 3manifolds
I just learned from Jesse Johnson’s blog that Vlad Markovic and Jeremy Kahn have announced a proof of the surface subgroup conjecture, that every complete hyperbolic manifold contains a closed injective surface. Equivalently, contains a closed surface subgroup. Apparently, Jeremy … Continue reading
