Definition
- A bitopological space (X, τ_1, τ_2) is MN pairwise R_0 in the sense of Murdeshwar and Naimpally (briefly MN-p-R_1) if for every pair of points implies that x has a 2-neighbourhood and y has a 1-hieghbourhood which are disjoint.
Property
- If a bitopological space is MN-p-R_1, it is R-p-R_1.
