Cadlag function
WebA function is cadlag (from the French \continue a droit, limite a gauche") if it is right-continuous with left limits. In his classical paper [Sko56], Skorohod introduced four topologies on the space of real cadlag functions on a compact interval, which he called J1, J2, M1, and M2.

The choice, among all others, of assuming cadlag trajectories for financial modeling is justified by the following arguments. If a cadlag trajectory has a jump at time t, then the value of X t(ω) is unknown before tfollowing the trajectory up to time t: the discontinuity is a ...
