A note on 'The modularity law in some classes of aggregation operators'

摘要

In this paper, the study of the functional equation of modularity for 2-uninorms recently published by Fechner, Rak and Zedam is revisited. A result from Corollary 6.3 in the mentioned paper is corrected and it is now given in a correct form. Furthermore, we characterize more general cases of modularity for 2-uninorms.
