The left (right) distributivity of semi-t-operators over ۲-uninorms

Recently the distributive equations involving various classes of aggregation operators have aroused widespread attention because of their importance in the theoretic and applied communities of fuzzy set theory. ۲-uninorms and semi-t-operators are two special classes of aggregation operators and have been proved to be useful in many areas such as fuzzy decision making, approximate reasoning and so on. Therefore, the aim of this paper is to investigate the left (right) distributivity of semi-t-operators over ۲-uninorms. We consider five subclasses of ۲-uninorms and characterize the corresponding left (right) distributive equations of semi-t-operators over ۲-uninorms.
