Characterizations of \(\Lambda_\theta-R_0\) and \(\Lambda_\theta-R_1\) topological spaces
\(\Lambda_\theta-R_i\) (\(i\in \{0,1\}\)) topological spaces are introduced, via the concepts of \((\Lambda,\theta)\)-closure operator and \((\Lambda,\theta)\)-open set. Basic properties of these are being established, as well as a lot of useful characterizations.
