Query: Firm non-expansive mappings in weak metric spaces   We introduce the notion of firm non-expansive mapping in weak metric spaces,
extending previous work for Banach spaces and certain geodesic spaces. We prove
that, for firm non-expansive mappings, the minimal displacement, the linear
rate of escape, and the asymptotic step size are all equal. This generalises a
theorem by Reich and Shafrir.
