I am interested in to varying degrees ordered sets, general topology, point-free topology, Boolean algebras, set-theory, universal algebra, and model theory. Most of my mathematics research involves dualities that are similar to Stone duality.

comment Characterizing Inf and Sup sets
If you don't like writing $\textrm{Inf}(\leq)$, then you could write $\textrm{Inf}(X,\leq)$ instead. And writing $\textrm{Inf}(\leq)$ is not any more ambiguous than writing $\textrm{Inf}(R)$.

comment Characterizing Inf and Sup sets
user47958. Writing $(X,R)$ for a partially ordered set is not a standard practice. I do not recall ever seeing a mathematician use $R$ for a partial ordering relation. Usually one writes $\leq$ or maybe even $\preceq$ for a partially ordering.

I have edited this question. Now it should be much more answerable and clear what I am looking for.

Mirko. Thanks for providing the link to that paper.
