Form equivalence class Howard-Rubin Number: 14
Statement: Wallman's Lemma. Assume \(\Cal C =\{ C_j : j\in J\}\) is a family of finite sets. For each \(j\in J\),let \(b_j =\bigcup C_j\) and assume that the family \(\{ b_j : j\in J\}\)has the finite intersection property. Then there is a choicefunction \(f\) for \(\Cal C\) such that \(\{ f(C_j) : j\in J\}\) hasthe finite intersection property. Cowen [1983].
