Title: An invitation to coherent groups.
A group is coherent if every finitely generated subgroup is finitely presented. The goal of this minicourse is to survey the ideas, examples, theorems, and open problems related to coherent groups. The lectures will be individual forays into the various topics. They will engage with quasiconvexity, local indicability, orderability, morse theory, small-cancellation theory, and aspects of combinatorial group theory that involve geometric thinking about the fundamental group that isn’t quite geometric group theory, but is rather closer to the still nascent theory of one-relator groups.
