Abstract

It has been recently shown that the Bellman function method can be applied in the general context of Gundy's extrapolation theorem for vector-valued martingales. But the additional assumption has been made that martingales are adapted to a certain special filtration. Here it is shown that those results can be extended to any regular filtration.
