Witrynapcl(A) and is defined by the intersection of all pre closed sets containing A. Definition 2.5. [5] A subset A of a topological space (X, τ) is said to be pre*generalized pre closed set (briefly p*gp-closed) if pcl(A) U whenever A U and U is pre*open in (X, τ). The collection of all p*gp-closed sets of X is denoted by p*gp-C(X). Lemma 2.6. WitrynaLemma 3.2. Every RL-closed set is a locally closed set. Proof. Let A be a RL-closed set in a topological space(X,τ). Then, A = U ∩V , where U is regular open set and V is closed set in (X,τ). As every regular open set is open, we have A is a locally closed set. Proposition 3.1.
