Hardy Martingales and the Unconditional Convergence of Martingales

Bulletin of the London Mathematical Society, 1991
The class of Hardy martingales is introduced. These are martingales taking values in a complex Banach space whose increments, conditional on the past, are in the appropriate Hardy space. Such martingales are plurisubharmonic, and so every \(L^ 1\) bounded Hardy martingale which connverges in probability also converges in norm.

Martingales [PDF]

open access: yes, 2010
This thesis deals with martingales and other subjects that are closely connected with this area. It provides an overview of the theory regarding Markov times, compensators, martingales themselves and other related topics, for instance martingale measures

Martingale Boosting

2005
Martingale boosting is a simple and easily understood technique with a simple and easily understood analysis. A slight variant of the approach provably achieves optimal accuracy in the presence of random misclassification noise.

Quantum Martingales that are Reverse Martingales are Multiples of the Identity

Bulletin of the London Mathematical Society, 1984
Let \({\mathcal C}\) be a hyperfinite \(II_ 1\) factor, m the normal faithful central state (probability trace) on \({\mathcal C}\). For \(1\leq p\leq \infty\) define \(L^ p({\mathcal C})\) to be the completion of \({\mathcal C}\) with respect to the \(L^ p\)-norm \(\| u\|_ p=m(| u|^ p)^{1/p},\) \(u\in {\mathcal C}\).

On Wolff's Pasta Martingale

Operations Research, 1992
In establishing the seminal result PASTA (Poisson Arrivals See Time Averages), R. Wolff (1982) constructed a martingale, and demonstrated that PASTA was a consequence of a strong law of large numbers of this martingale. Here we establish a central limit theorem for the PASTA martingale, and characterize its asymptotic normality. The result can be used

On martingales and feller semigroups

Results in Mathematics, 1992
The author gives a clean characterization theorem which stems from the work of \textit{D. W. Stroock} and \textit{S. R. S. Varadhan} [Multidimensional diffusion processes (1979; Zbl 0426.60069)] on martingale problems in multidimensional diffusion. Let \(E^ \Delta\) be the one point compactification of the locally compact Hausdorff space \(E\).
