The subject of this paper is the study of the $\sigma$-field on $
R_+\times\Omega$ generated by a family of cadlag processes including the deterministic ones, and stable under stopping at non-random times. Of course the optional and previsible $\sigma$-fields are Meyer $\sigma$-fields in this very general sense. It is a matter of wonder to see how far one can go with such simple hypotheses, which were suggested by Dellacherie

1524 for an interesting application. The work of Fourati (partly unpublished) follows along the same lines, but including time reversal: see
