Sur la convergence absolue de certaines intégrales (General theory of processes)
This paper is devoted to the a.s. absolute convergence of certain random integrals, a classical example of which is $\int_0^t ds/|B_s|^{\alpha}$ for Brownian motion starting from $0$. The author does not claim to prove deep results, but his technique of optional increasing reordering (réarrangement) of a process should be useful in other contexts too
Comment: This paper greatly simplifies a proof in the author's Semimartingales et Grossissement de Filtrations, LNM 833, p.44
Keywords: Enlargement of filtrations
