Generalized Ito Formula, Change of Time and Measure, Brownian motion is truly the canonical example of a continuous local martingale. Namely, if . is a continuous local martingale with quadratic variation [.] . , then there is a random change of time . such that {.,. ∈ . } is a Brownian motion up to the (random) time [.]. = sup..[.]..
