Soit {An}n=1 une séquence d'événements dans un éspace de probabilité (Ω,F,P). On montre que, si limmn=1mwnP(An)= où chaque wnR, alors

P(lim supAn)lim supn(k=1nwkP(Ak))2i=1nj=1nwiwjP(AiAj).

Let {An}n=1 be a sequence of events on a probability space (Ω,F,P). We show that if limmn=1mwnP(An)= where each wnR, then

P(lim supAn)lim supn(k=1nwkP(Ak))2i=1nj=1nwiwjP(AiAj).
