WebJan 24, 2024 · Abstract. We introduce Orlicz–Hardy spaces for two-parameter martingales, and establish some new martingale inequalities by use of the atomic decompositions. We also characterize the dual spaces of martingale Orlicz–Hardy spaces in two-parameter case as the generalized martingale Lipschitz spaces. Download to read the full article text.

Let ( X n: n ≥ 1) be a sequence of iid random variables (say, on a probability space ( Ω, F, P)) with common density g. Suppose that f is another density with the property that whenever g ( x) = 0, … WebIn probability theory, a Lévy process, named after the French mathematician Paul Lévy, is a stochastic process with independent, stationary increments: it represents the motion of a point whose successive displacements are random, in which displacements in pairwise disjoint time intervals are independent, and displacements in different time …
WebAug 20, 2014 · As applications we show the relation among five martingale Orlicz-Hardy spaces and the duality, namely, the dual of martingale Orlicz-Hardy spaces are generalized martingale Campanato spaces. WebStout (1970) generalized the LIL to stationary ergodic martingales. Wittmann (1985) generalized Hartman–Wintner version of LIL to random walks satisfying milder conditions.

WebSep 1, 2006 · Our generalized spectral martingale test rejects the null hypothesis (3) for large values of D n 2. Notice that D n 2 uses all the n-1 lags contained in the sample, so we have not to choose any lag order parameter. Note the similarity between (8) and (14).

The Average Amounts Bet Because !k 1 is independent of bk 1 and the average of an independent product is the product of the averages, the average amount bet on the kth
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. The strategy had the gambler double their bet … See more In probability theory, a martingale is a sequence of random variables (i.e., a stochastic process) for which, at a particular time, the conditional expectation of the next value in the sequence is equal to the present … See more • An unbiased random walk (in any number of dimensions) is an example of a martingale. • A gambler's fortune (capital) is a martingale if all the betting games which the gambler plays are fair.
