FUZZY CHU SPACES AND FUZZY TOPOLOGIES

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2004
We show that each fuzzy (or in general L-) topological space can be represented as a fuzzy (or an L-) Chu space. Further, this representation preserves products, coproducts, tensor products, and hom-sets (together with the structures they are enriched with).

L-fuzzy topological groups

Fuzzy Sets and Systems, 1991
The concept of \(L\)-fuzzy topological groups is introduced as follows: Let \(X\) be a group and \(J\) be an \(L\)-fuzzy topology on \(X\). The pair \((X,J)\) is said to be an \(L\)-fuzzy topological group, if and only if the following conditions are satisfied: (a) The mapping \(g: (x,y)\to xy\) of the product \(L\)-fuzzy topological space \((X,J ...

T-product fuzzy topology

Fuzzy Sets and Systems, 1993
The \(T\)-product \(\tau_ 1 \otimes_ T \tau_ 2\) on \(X_ 1 \times X_ 2\) of fuzzy topological spaces \((X_ 1, \tau_ 1)\) and \((X_ 2, \tau_ 2)\) is defined. Some properties of the \(T\)-product are proved. The projection mappings \(p_ i : {(X_ 1 \times X_ 2, \tau_ 1 \otimes_ T \tau_ 2)}\) \(\to (X_ i, \tau_ i)\), \(i = 1,2\), are continuous. If \((X_ i,

Fuzzy topology on fuzzy sets: Product fuzzy topology and fuzzy topological groups

Fuzzy Sets and Systems, 1998
Considering the notion of fuzzy topology on fuzzy sets [\textit{M. K. Chakraborty} and \textit{T. M. G. Ahsanullah}, ibid. 45, No. 1, 103-108 (1992; Zbl 0754.54004)] the present author introduces the concept of product fuzzy topology and investigates the product invariance of fuzzy Hausdorffness, compactness and connectedness.
