Before revision:  To elaborate those coupling maps, we will briefly use "optimal transport theory" as a starting point, then we will derive two main families of criteria: those based upon "statistical independence" versus those based upon "logical indetermina-tion ".
After revision:  To elaborate those coupling maps, we will briefly use "optimal transport theory" as a starting point, and a way as well, to derive two canonical couplings: "statistical independence" versus those based upon "logical indetermina-tion ".
