A Stone-type duality for Meet Semilattices
by
Aditya Nagrath
University of Denver

We generalize Priestley duality to arrive at a duality for an interesting category of bounded meet semilattices with two natural properties. The dual objects of the meet semilattices are a category of topological spaces endowed with a ternary relation called betweenness. As with Priestley duality, our duality results from what is known categorically as a full duality between the two categories in question.
