Shortest Axiomatizations of Implicational S4 and S5
Shortest possible axiomatizations for the implicational fragments of the modal logics S4 and S5 are reported. Among these axiomatizations is included a shortest single axiom for implicational S4--which to our knowledge is the first reported single axiom for that system--and several new shortest single axioms for implicational S5. A variety of automated reasoning strategies were essential to our discoveries.
