Form equivalence class Howard-Rubin Number: 1
Statement:
If \((X,T)\) is a \(T_4\) topological space and \(U =\{U_i: i\in K\}\), \(|U_i|\ge 2\), is a locally finite family ofopen non-empty pairwise disjoint sets, then there is a continuous real valued function \(f\) on \(X\) which assumes at least two distinct values on each \(U_i\).

These are definitions from Brunner [1982b] and results similar to the equivalence of [8 C] and [8 D] to Form 8 and [10 H] to Form 10. We also include some results from Brunner [1987b].
