Topological structures of intuitionistic fuzzy rough sets

TL;DR: It is shown that an intuitionistic fuzzy rough approximation space can induce an intuitionism fuzzy topological space if and only if the intuitionistic fuzziness relation in the approximation space is reflexive and transitive.

Fuzzy Semi Open Soft Sets Related Properties In Fuzzy Soft Topological Spaces

TL;DR: This paper investigates the properties of fuzzy semi open (closed) soft sets, fuzzy semi soft interior (closure), fuzzy semi continuous (open) soft functions and fuzzy semi separation axioms which are important for further research on fuzzy soft topology and forms the theoretical basis for further applications of topology on soft sets.

The lattice of ordinary smooth topologies

TL;DR: In this paper, a collection of OST(X) topologies is studied, and it is shown that OST (X) is a complete lattice, in the sense of a lattice.
