There exist multiple variants of the original definition. Here we prove that most of them are indeed equal. One central point is to correct the proof of Brakke's §3.5, where he develops an estimate for the evolution of the measure of time-dependent test functions.Mean curvature flowWeak & singular flowsLimit spaces & RCD
