Cadlag function

WebAbstract. This chapter considers the space D, of functions on the unit interval that are continuous on the right with left limits. D contains and extends the space C, but is nonseparable, so to work with it calls for new techniques. By defining a new topology for D (the Skorokhod topology) families of measures on D can be constructed and ... WebDepartment of Mathematics – University of Wisconsin – Madison – UW–Madison

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. Of these, http://www.stat.yale.edu/~pollard/Courses/603.fall04/notes/project7.pdf
