In mathematics, in the field of topology, a topological space is said to be pseudonormal if given two disjoint closed sets in it, one of which is countable, there are disjoint open sets containing them. [1] Note the following:
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]
