Cofinite subsets and double negation topologies on locales of filters and ideals
Luis Español, José Manuel García-Calcines, M. Carmen Mínguez
We study the role of the filter of cofinite subsets of in the locale of all filters on , by means of the double negation topology of $\…
On proper and exterior sequentiality
L. Espanol, J. M. Garcia Calcines, M. C. Minguez
In this article a sequential theory in the category of spaces and proper maps is described and developed. As a natural extension a sequential theory for exterior spaces and maps is…
Quasitopoi over a base category
Eduardo J. Dubuc, Luis Español
In this paper we develop the theory of quasispaces (for a Grothendieck topology) and of concrete quasitopoi, over a suitable base category. We introduce the notion of f-regular cat…
Topological functors as familiarly-fibrations
Eduardo J. Dubuc, Luis Español
In this paper we develop the theory of topological categories over a base category, that is, a theory of topological functors. Our notion of topological functor is similar to (but…
