Colimit theorems for coarse coherence with applications
Boris Goldfarb, Jonathan L. Grossman
We establish two versions of a central theorem, the Family Colimit Theorem, for the coarse coherence property of metric spaces. This is a coarse geometric property and so is well-d…

Coarse coherence of metric spaces and groups and its permanence properties
Boris Goldfarb, Jonathan L. Grossman
We introduce properties of metric spaces and, specifically, finitely generated groups with word metrics which we call coarse coherence and coarse regular coherence. They are geomet…
