Some Remarks on the Characterization of Idempotent Uninorms

摘要

In this paper the characterization of idempotent uninorms given in [21] is revisited and some technical aspects are corrected. Examples clarifying the situation are given and the same characterization is translated in terms of symmetrical functions. The particular cases of left-continuity and right-continuity are studied retrieving the results in [7]. Uninorm, idempotent uninorm, symmetrical function, left-continuity
