A NOTE ABOUT OPERATIONS LIKE T-W (THE WEAKEST t-NORM) BASED ADDITION ON FUZZY INTERVALS
We investigate a relation about subadditivity of functions. Based on subadditivity of functions, we consider some conditions for continuous t-norms to act as the weakest t-norm T-W-based addition. This work extends some results of Markova-Stupnanova [15], Mesiar [18].
