Isbell duality

##
Michael Barr, John F. Kennison, and R. Raphael

We develop in some generality the dualities that often
arise when one object lies in two different categories. In our
examples, one category is equational and the other consists of the
topological objects in a (generally different) equational category.

Keywords:
duality, fixed categories, sober objects
