Bornologies and Lipschitz Analysis
The largest bornology is the power set of the space and the smallest is the bornology of its finite subsets. Between these lie (among others) the metrically bounded subsets, the relatively compact subsets, the totally bounded subsets, and the Bourbaki bounded subsets.

In this con-text, we are also able to bypass many of the issues involved in the topological analysis of vector spaces.

Bornological convergences and local proximity spaces
Let (X, δ, B) be a local proximity space. Apparently, in the beginning, we have two natural different ways to topologize the hyperspace C L (X) of all closed non-empty subsets of X.A first option calls upon the dense embedding of X in the natural T 2 local compactification ℓ (X), while a second one stems from joining together proximity and bornology in a hit and far-miss …

bornological set in nLab
If X X is any topological space such that every point is closed, then there is a bornology consisting of all precompact subsets of X X (subsets whose closure is compact). Any continuous map is bounded with respect to this choice of bornology. If X X is any metric space, there is a bornology where a set is bounded if it is contained in some open ...

A bornology B on X is tall if and only if B∧ is nowhere dense in X∗. A bornology B on X is antitall if and only if B∧ has a dense subset open in X∗. Every bornology on X is the intersection of some tall and antitall bornologies. Proposition 2. For a bornology B on X, the following statements are equivalent: (i) B is antitall;

A typical example is a bornology generated by a metric, i.e. the collection of all bounded sets for that metric. In a recent paper [E. Colebunders, R. Lowen, Metrically generated theories, Proc.

Abstract. arXiv:1807.03028v2 [math.GN] 15 Nov 2018
By [15, Proposition 1], every bornology is the meet of some tall and antitall bornologies. A family B′ ⊆ B is called a base of a bornology B if each set B ∈ B is contained in some set B′ ∈ B′. Every bornology with a countable base is antitall. In particular, the bornology of all bounded subsets of a metric space is antitall.
