Inductive Constructions using Finite Hulls
by

We define a topological space X by a simple inductive procedure of length omega₁. The actual space described depends on the particular sequence of finite hulls but, for sufficiently large finite hulls, its properties appear to be rather coherent and its structure surprisingly stable. By using appropriate parameters, we can obtain some well-known and useful spaces.
