“…There is a wide literature treating this subject (we refer to [1], [9], [13], [14] in the single-valued case and to [8], [11], [31], [37] in the set-valued setting). The motivation comes from the fact that one can thus cover the framework of usual differential problems (when g is absolutely continuous), of discrete problems (when g is a sum of step functions), of impulsive equations (for g being the sum between an absolutely continuous function and a sum of step functions), as well as retarded problems (see [1]). As proven in [13], dynamic equations on time scales and generalized differential equations can also be seen as measure differential equations.…”
