Probabilistic Approach to Regularity
We here gather in a single note several original probabilistic works 4 devoted to the analysis of the C1,1 regularity of the solution to the possibly 5 degenerate complex Monge–Ampère equation. The whole analysis relies on a 6 probabilistic writing of the solution as the value function of a stochastic 7 optimal control problem. Such a representation has been introduced by 8 Gaveau [Gav77] in the late 1970s and used in an exhaustive way by Krylov in 9 a series of papers published in the late 1980s up to the final paper [Kry89] in 10 which the C1,1-estimate is eventually established. All the arguments we here 11 use follow from these seminal works.
