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
geometric counterparts of the classical algebraic notion of coherence and
the regular coherence property of groups defined and studied by Waldhausen.
The new properties can be defined in the general context of coarse metric
geometry and are coarse invariants. In particular, they are quasi-isometry
invariants of spaces and groups. The new framework allows us to prove
structural results by developing permanence properties, including the
particularly important fibering permanence property, for coarse regular
coherence.
