Abstract
This note studies the subcategory of pairwise-T 2 spaces in the category of bitopological spaces. Epimorphisms are characterized by means of an additive closure operator 2h. Non-cowellpoweredness is shown and properties of 2h are investigated.
Grants from the University of the North are acknowledged, despite incompetent management. Parts of this paper was written at the University of Cape Town.
