We study some almost everywhere convergence problems for martingales. We establish various equivalency theorems, which show that in some problems of martingales theory the general martingales can be replaced by Haar martingales. Some applications of the obtained results to the theory of differentiation of integrals and convergence of Riemann sums are also discussed. 相似文献

We prove the everywhere divergence of series $$ \sum_{n=0}^\infty a_n e^{i\rho_n}e^{inx}, \quad\text{and}\quad \sum_{n=0}^\infty {(-1)}^{[\rho_n]}a_n \cos nx, $$ for sequences a n and ρ n satisfying some extremal conditions. These results generalize some well known examples of everywhere divergent power and trigonometric series. 相似文献
