Variable-Basis Fuzzy Filters

U. H{ö}hle and A. {Š}ostak have developed in \cite{HS} the category of complete quasi-monoidal lattices; S. E. Rodabaugh in \cite{RO} proposed its opposite category and with a subcategory $\mathbf{C}$ of the latter, he define grounds of the form $\mathbf{SET\times C}$. In this paper, for each ground category of the form $\mathbf{SET\times C}$, we study categorical frameworks for variable-basis fuzzy filters, particularly the category $\mathbf{C-FFIL}$ of variable-basis fuzzy filters, as a natural generalization of the category of fixed-basis fuzzy filters which was introduced in \cite{LO}. In addition, we get some relations between the category of variable-basis fuzzy filters and the category of variable-basis fuzzy topological spaces.

Interior Operators and Topological Categories

The introduction of the categorical notion of closure operators has unified various important notions and has led to interesting examples and applications in diverse areas of mathematics (see for example, Dikranjan and Tholen (\cite{DT})). For a topological space it is well-known that the associated closure and interior operators provide equivalent descriptions of the topology, but this is not true in general. So, it makes sense to define and study the notion of interior operators $I$ in the context of a category $\mathfrak C$ and a fixed class $\mathcal M$ of monomorphisms in $\mathfrak C$ closed under composition in such a way that $\mathfrak C$ is finitely $\mathcal M$-complete and the inverse images of morphisms have both left and right adjoint, which is the purpose of this paper.
