(1,2)*-Pre-Λ-Sets and (1,2)*-Pre-V-Sets

In this paper, we introduce the notions of (1,2)* -pre-Λ-sets and (1,2)* -pre-V -sets in a bitopological space and study their fundamental properties. We also introduce two new spaces called (1,2)* -pre-T1 and (1,2)* -pre-R0-spaces.Characterization of these spaces are done using (1,2)* -pre-Λ-sets and (1,2)* -pre-V -sets.
