On product fuzzy topological spaces

Some Features α-T₀ Spaces in Supra Fuzzy Topology

“…Thus we see that every fuzzy topology is supra fuzzy topology but the converse is not always true. (Mashhour et al 1983).…”

“…The elements of t * are called supra open sets in (X, t * ) and complement of supra open set is called supra closed set (Mashhour et al 1983).…”

“…Chang (1968) and Lowen (1976) developed the theory of fuzzy topological spaces using fuzzy sets. Mashhour et al (1983) introduced supra topological spaces and studied s-continuous functions and s * -continuous functions. They also gave the concept of -T 0 fuzzy topological spaces.…”

Supra b-compact and supra b-Lindelof spaces

“…In 1983, A. S. Mashhour et al [3] introduced the supra topological spaces. In 1996, D. Andrijevic [1] introduced and studied a class of generalized open sets in a topological space called b-open sets.…”

“…X is called a supra topology [3] on X if X ∈ µ and µ is closed under arbitrary union. (X, µ) is called a supra topological space.…”
