Addendum to 'On the migrativity of uninorms and nullnorms over overlap and grouping functions' Fuzzy Sets Syst. 346 (2018) 1-54

摘要

Recently, Qiao and Hu have investigated the alpha-migrativity of uninorms and nullnorms over overlap functions and grouping functions (Qiao and Hu, 2018 [38]). However, the alpha-migrativity of overlap functions and grouping functions over uninorms and nullnorms is missing. In this paper, as a supplement of the above paper, we investigate the alpha-migrativity of overlap functions and grouping functions over uninorms and nullnorms. Moreover, we point out that some but not all similarities and differences between the alpha-migrativity of a uninorm U (resp. nullnorm F) over an overlap function O (resp. grouping function G) and the alpha-migrativity of an overlap function O (resp. grouping function G) over a uninorm U (resp. nullnorm F).
