....of classical provability logic GL: I 4 = U Phi (2p , p) p: The logic I 4 is characterized by the class of irreflexive Kripke frames without infinite ascending chains, i.e. by the same frames as GL but with a different interpretation of the implication. Another example is due to Yashin [29] who showed that the logic Y = I 4 Phi 22p , p , q) q , p) is Novikov complete in the sense that 2 is not definable in Int (it is a new intuitionistic connective ) and Y is a maximal logic in NExtU which is conservative over Int. Kuznetsov and Muravitskij [17] proved that there is a ....
