In this paper, we study uni-nullnorms and null-uninorms on bounded lattices, which are generalizations of uninorms, nullnorms, t-norms and t-conorms. We construct two uni-nullnorms and two null-uninorms on a bounded lattice ...

Nullnorms are generalization of triangular norms and triangular conorms with a zero element in the interior of the unit interval. in this paper, we generalize nullnorms to an arbitrary bounded lattices. We show the existence ...
