M. We studied and introduced a concept SIVFT then present the concept of SIVF subspace and SIVF product topology in SIVF topological spaces. W-Hausdorff Separation Axiom in SIVF topological spaces and its basics are studied. 2025 2025 221 228 10.54216/IJNS.260315 https://www.americaspg.com/articleinfo/21/show/3794
