Variants of Essential Arity for Partial Functions

Erkko Lehtonen*, Nareupanat Lekkoksung

Kyungpook Mathematical Journal 2020; 60: 423-443

Generalizations of essential arity of partial functions, based on essential sets of arguments, are introduced, and their interplay with the minor relation of functions is investigated.

Purities of Ordered Ideals of Ordered Semirings

Pakorn Palakawong na Ayutthaya, Bundit Pibaljommee*

Kyungpook Mathematical Journal 2020; 60: 455-465

We introduce the concepts of the left purity, right purity, quasi-purity, bipurity, left weak purity and right weak purity of ordered ideals of ordered semirings and use them to characterize regular ordered semirings, left weakly regular ordered s...
