DMF-algebras: Representation and topological characterization
1998A partial set on \(X\) is an ordered couple \((A,B)\) of subsets of \(X\) such that \(A\cap B=\emptyset\). A DMF-algebra is a De Morgan algebra with a single fixed point for negation. Partial sets on \(X\) can be endowed with a structure of DMF-algebra, and any DMF-algebra is isomorphic to a field of partial sets.
