Cadlag function
Webdict.cc German-English Dictionary: Translation for legale Funktion WebThe space of all real-valued cadlag functions is denoted by D(T). 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 ...
