Partial linear spaces built on hexagons
3 We define four families of geometries with as point graph the graph — or its complement — of all elliptic 4 hyperplanes of a given parabolic quadric in any finite 6-dimensi...

A Resolution Calculus with Shared Literals
We present a resolution calculus for first-order logic using a more concise formalism for representing sets of clauses. The idea is to represent the clause set at hand as a Direct...
