Intersections between some families of (U, N)- and RU-implications

U,N)-implications and RU-implications are the generalizations of (S,N)and R-implications to the framework of uninorms, where the t-norms and t-conorms are replaced by appropriate uninorms. In this work, we present the intersections that exist between (U,N)-implications and the different families of RU-implications obtainable from the well-established families of uninorms.
