摘要:What is the probability (called persistence) that a real stochastic variable has not changed its initial sign up to time $t$?

Answer: this is the same tau-function (Chazy, 1911) of a codimension-three sixth Painleve' equation  than the one of the mean curvature of Bonnet surfaces (Bonnet, 1867).
