“…In fact, t-norms (t-conorms) have been widely studied on bounded lattices by many authors (see, e. g., [8,12,18,21,22,23,30,34,35,38,44,45]), including the constructions of t-norms (t-conorms), especially in the construction of ordinal sums of t-norms (t-conorms). Then, uninorms have been extensively investigated on bounded lattices [7] and the constructions of uninorms are usually based on these tools, such as t-norms (t-conorms) (see, e. g., [1,4,5,6,9,10,11,13,15,19,20,32,33,47,49]), t-subnorms ( t-superconorms) (see, e. g., [29,31,49,52]), closure operators (interior operators) (see, e. g., [14,27,39,51]), additive generators [28] and uninorms (see, e. g., [16,48]).…”
