Applications of Multisets Affected by Primal Collections in Topological Spaces

This paper extends the classical approach of primal topology by embedding the multiset model. In multiset theory, the element multiplicity plays a fundamental structural role using the family [T]α of multisets defined over a base set T. Here, we introduce the notion of an M-primal collection and investigate its induced topological behavior. Within this setting, we define and study local M-functions, which describe specific interactions between multiplicity and primal structures. These functions lead to the development of a stronger form of M-primal topology, improving the current multiset topological space. Several properties of the introduced concept are investigated, as well as relationships and examples. The results illustrate that the introduced concept is richer and more modifiable.
