Resumen

In this paper, we show that a pointwise ? -symmetric ? -isotonic ? -closure function is uniquely determined by the pairs of sets it separates. We then show that when the ? -closure function of the domain is ? -isotonic and the ? -closure function of the codomain is ? -isotonic and pointwise- ? -symmetric, functions which separate only those pairs of sets which are already separated are ? -continuous.
