Mixed connectives between min and max

Mixed connectives are types of aggregate operators for fuzzy sets constructed from t-norms. Since these operators are situated between the fuzzy logical connective 'and' modeled by a t-norm and the connective 'or' modeled by a t-conorm, their parametric dependence tells how near they are from these two connectives and allows families of mixed connectives to be considered. The existence of elements in such a family situated between min and max is studied.<>
