We give sound and complete tableau and sequent calculi for the propositional normal modal logics $4.04, K4B and G O (these logics axe the smallest normal modal logics containing K and the schemata [:]A -+ ODA, DA --+ A and D<)DA --+ (A --+ DA) ; DA -+ D[]A and A -+ D<>A ; DA --+ D[qA and D(D(A --+ D
By fuzziΓΏcation we mean a procedure which assigns a fuzzy logic to an arbitrary crisp logic. In this paper we describe two essentially di erent fuzziΓΏcation procedures. In order to give a formal description of the notion of fuzziness of a formula, we extend the language of the propositional logic by
