“…S k is used to represent kfold product space of any complete and separable metric space S for k ∈ N. For a complete separable metric space S, D([0, ∞), S) denotes the space of all S-valued càdlàg functions on [0, ∞), and is endowed with the Skorohod J 1 topology (see, e.g., [7,14,58] is the space of all S-valued "continuous from above with limits from below" functions on [0, ∞) 2 , and is endowed with the same metric as defined by [19]. D 2 ≡ D([0, 1] 2 , R) is denoted as the space of all "continuous from above with limits from below" functions on the unit square [0, 1] 2 in the sense of Neuhaus [39], and is endowed with the same metric d D 2 as in [39].…”
