The topological notion of m-filter
by
Manuel Suarez
UPTC, Tunja, Colombia
Coauthors: Edilberto Sarmiento (U. Javeriana, Bogotá, Colombia)

It is well known that neighborhoods, filters and convergent filters are associated with the topological functions of interior. In this paper similar notions are defined using the topological functions of boundary, coboundary, h and ch. To describe this in categorical terms, a restriction of comma category is used.

(The talk will be delivered in Spanish)
