This paper explores interaction operators utilized within the framework of the inclusion and exclusion integral (IE-integral).

摘要

This paper explores interaction operators utilized within the framework of the inclusion and exclusion integral (IE-integral). Specifically, we introduce a novel duality concept for interaction operators and the associative and commutative binary operators (AC-operators) that produce them. These concepts are derived from the conventional duality of set functions through the framework of IE-integrals. Moreover, we reframe IE-integrals and the aforementioned new concepts from the standpoint of discrete derivatives.
