On $\lambda_b$-Sets and the Associated Topology $\tau_b ^{*}$

Authors: M. Caldas, Saeid Jafari, T. Noiri

In this paper we define the concept of $\Lambda_b$-sets (resp. $V_b$-sets) of a topological space, i.e., the intersection of b-open (resp. the union of b-closed) sets. We study the fundamental property of $\Lambda_b$-sets (resp. $V_b$-sets) and investigate the topologies defined by these families of sets.
