Stochastic integrals and BDG's inequalities in Orlicz-type spaces

Yingchao Xie, Xicheng Zhang

Published 2016-06-14Version 1

In this paper we extend an inequality of Lenglart, L\'epingle and Pratelli \cite[Lemma 1.1]{LLP} to general continuous adapted stochastic processes with values in topology spaces. By this inequality we show Burkholder-Davies-Gundy's inequality for stochastic integrals in Orlicz-type spaces (a class of quasi-Banach spaces) with respect to cylindrical Brownian motions.
