Quote: two regions of state space are 'separated' if their intersection is closed, 'joined' if the intersection is open, and 'inseparable' if same frame

Note

two regions are separated if the intersection of their frames is a closed set, they are joined if the intersection of their frames is an open set., they are inseparable if both regions are in the intersection of their frames. This corresponds to T0, T1, and T2 separation respectively
