报告题目:Ordinal sums of triangular norms on bounded lattices
报 告 人:刘华文,山东大学数学学院教授
报告摘要:In this talk, we focus on the ordinal sum constructions of triangular norms (t-norms for short) on bounded lattices. First, we present a construction method for t-norms and establish the necessary and sufficient conditions for this kind of construction by order-preserving unary functions on bounded lattices. Then, we simplify these conditions for practical use. Further, a new type of ordinal sum constructions which can cover many existing constructions for t-norms on bounded lattices is proposed. The obtained results may inspire new methods for constructing other fuzzy connectives and will be important for further studies about the characterization of t-norms on bounded lattices.
