Kuznetsov independence of variables X and Y means that, for any pair of bounded functions f(X) and g(Y ), E [f(X)g(Y )] = E [f(X)] E [g(Y )], where E [·] denotes interval-valued expectation and denotes interval multiplication. We present properties of Kuznetsov independence for several variables, and connect it with other concepts of independence in the literature; in particular we show that st...
