WebDoob’s Optional Stopping Theorem). We begin with some preliminaries on measure-theoretic probability theory, which allows us to discuss the de nition and basic properties of martingales, We then state some auxiliary results and use them to prove the main theorem. 1 Introduction Recall that a martingale is (informally) a random process X= fX WebThe martingale was originally a type of betting style based on the premise of "doubling down."
