Abstract: Kelly initiated the study of bi-topological spaces in [3]. In this paper the concepts of pairwise-T, pairwise regular, pairwise Hausdorff, quasi-pseudo-metrizable, and quasi-metrizable are introduced, and the following theorem is proved. Theorem. If (X, P, Q) is a pairwise regular bi-topological space satisfying the second axiom of countability, then (X, P, Q) is quasi-pseudo-metrizable. If in addition (X, P, Q) is pairwise Hausdorff, it is quasi-metrizable. The concepts underlying the above definitions do not easily rarry over to concepts such as pairwise compact, pairwise connected, and pairwise continuous, as is partially demonstrated in [2]. This author was therefore led to investigate other possible ways for defining properties in bi-topological spaces. One idea investigated was that of bi-open sets. A similar idea has recently been studied in [1]. It is the purpose of this paper to introduce the concept of bi-open sets in bi-topological spaces and to demonstrate how properties of topological spaces can easily be expressed for bi-topological spaces.
