Two weeks ago, there was a very interesting conference in Montréal organized around Dani Wise’s work on subgroup separability properties for certain word-hyperbolic groups, namely those with “quasi-convex hierachies”. I’ve mentioned this work twice before. This time Dani gave about 12-15 hours of lectures. Stefan Friedl took notes and typed then up into a 21-page summary which you can read here.
