WebStout (1970) generalized the LIL to stationary ergodic martingales. Wittmann (1985) generalized Hartman–Wintner version of LIL to random walks satisfying milder conditions. Vovk (1987) derived a version of LIL valid for a single chaotic sequence (Kolmogorov … Originally, martingale referred to a class of betting strategies that was popular in 18th-century France. The simplest of these strategies was designed for a game in which the gambler wins their stake if a coin comes up heads and loses it if the coin comes up tails.
