Regularity and normality in ideal bitopological spaces




Bitopological spaces, Ideal bitopological spaces, Separation in bitopological spaces, Separation in ideal bitopological spaces


We introduce, and study, the regularity and normality in ideal bitopological spaces, absent subject in literature. Our definitions have the advantage of using only the open sets of the two underlying topologies. These new concepts represent generalizations of Kelly's concepts of pairwise regularity and pairwise normality. The extension of the T0, T1 and T2 axioms to these spaces is due to Caldas et al.
