On generalized \(R_0\) and \(R_1\) spaces
The author characterizes properties of \(R_{0}\) and \(R_{1}\) topological spaces for generalized topological spaces [\textit{Á. Császár}, Acta Math. Hung. 96, No. 4, 351--357 (2002; Zbl 1006.54003)] thereby obtaining and simplifying many results on semi-\(R_{0}(R_{1})\), pre-\(R_{0}(R_{1})\), \(\delta\)-pre-\(R_{0}(R_{1})\), \(\delta \)-semi-\(R_{0}(R_{1})\), \(\delta\)-\(R_{0}(R_{1})\), \(\alpha\)-\(R_{0}(R_{1})\), \(\beta\)-\(R_{0}(R_{1}),\lambda\)-\(R_{0}(R_{1})\) and \(\Lambda_{\theta }\)-\(R_{0}(R_{1})\) topological spaces.
