Passing to a further subsequence if necessary, we may assume that in . Then from Proposition 3.64 and the continuity of h we have which contradicts (3.108). So, (3.110) holds ...

If the index in a martingale (respectively, submartingale, supermartingale) is replaced by two stopping times, does the main defining the process equality (respectively, inequality) remain true? The answer is “yes”, ...
