PS-Closedness in L-Topological Spaces
A new notion of PS-closedness is introduced in L-topological spaces, where L is a fuzzy lattice. PS-closedness is a weaker form of pre-semicompactness, and it is a stronger form of P-closedness and S *-closedness, respectively. It is a good L-extension of PS-closedness of topological spaces and preserves many good properties of closedness in topological spaces.
