On regularity of Banach-valued processes. (English) Zbl 0575.60004

The author obtains regularity properties for Banach lattice valued submartingales that generalize those of real valued submartingales or RNP-Banach martingales. He mainly uses stopping time method to replace the upcrossing-downcrossing trick which is not available in the vector valued case.
