In this paper, we lay bare some new formulas for calculating the upper and lower approximation left (right) semi-uninorms of a binary operation and further discuss the relations between the upper and lower approximation left (right) semiuninorms of a
In this paper, we study the relationships between left (right) semi-uninorms and implications on a complete lattice. We firstly discuss the residual operations of left and right semi-uninorms and show that the right (left) residual operator of a conj
