Convergence faible de processus, d'après Mokobodzki (
General theory of processes)
The following simple question of Benveniste was answered positively by Mokobodzki (
Séminaire de Théorie du Potentiel, Lect. Notes in M. 563, 1976): given a sequence $(U^n)$ of optional processes such that $U^n_T$ converges weakly in $L^1$ for every stopping time $T$, does there exist an optional process $U$ such that $U^n_T$ converges to $U_T$? The proof is rather elaborate
