... Suppose E and F are projections in a von Neumann algebra M ... ⇔ C(E) ≤ 1 - C(F), since 1 - C(F) is a central projection that dominates E ... In turn, the following is true Corollary Two projections E and F in a von Neumann algebra M contain two nonzero subprojections that are Murray-von Neumann equivalent if C(E)C(F) ≠ 0 ...
