Pseudonormal space
In
countable, there are disjoint open sets containing them.[1]
Note the following:
- Every normal space is pseudonormal.
- Every pseudonormal space is regular.
An example of a pseudonormal Moore space that is not metrizable was given by F. B. Jones (1937), in connection with the conjecture that all normal Moore spaces are metrizable.[1][2]
