curprev 20:5320:53, 18 April 2023 79.152.92.35 talk 34,971 bytes +63 The previous text incorrectly said that the symmetry of second derivatives is "known as Schwarz's theorem". This is false because the symmetry property itself is not what the theorem establishes: instead it identifies conditions under which exchangeability holds. undo Tag: Visual edit
