The transitive closure R′R′ of RR is the smallest transitive relation containing RR. For example if we had the following relation 1R21R2 and 2R32R3 then we do not have 1R31R3 or 1R11R1 but we have all of this in the reflexive transitive closure. Share Cite Follow answered Nov 16,...
In such approaches, both L and P(W ) are lattices, and the relation between L and P(W ) is materialized as an extension-intension lattice. This lattice is the structure of the definable elements of ...N. Caspard and B. Monjardet. The lattice of closure systems, closure operators and...
