The primary goal of this treatise is to introduce a new kind of generalized closed sets termed as Lgfs-closed sets in the light of fuzzy soft local function in a mixed fuzzy soft ideal topological space. Wealso define the notion of fuzzy soft ∗-separated set. In addition, we procure the idea of fuzzy soft regularity,normality and fuzzy soft compactness. We also study their behavior in terms of Lgfs-closed sets.
