For a Hausdorff space (X, 7) with a topology r and Y C X, let (X,7(X, Y)) be the space X with the topology 7(X, Y) defined by {G U B 1 G E T, B c Y}. We prove that in case (X, 7) is paracompact and perfectly normal with Y metrizable, (X,7(X; Y)) x (Y, T/Y) is normal iff Y is F, in (X, T). An example
