... theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. Several people have, since the 1950’s, proposed ways to generalize such formalisms from the classical to the manyvalued case. One particular method for systemat ...

... formation rule (iv) is strictly speaking not needed since the rule (iii) covers it. Concerning the rule (i), notice that also atoms of the type S(x, ..., x)k , where k 6= 1, are legitimate formulae. Let UF1 denote the set UF1 (T ). 3.1 Intuitions underlying the decidability proof We show decidabilit ...

Chapter 5 Predicate Logic
... We can use this latter interpretation of H to treat another predicate logic formula: (∀x)H(x, x). Here there is still only one quantifier and no connectives, but there is more than one quantified variable. The interpretation is that both arguments must be the same. This expression is true if H can p ...
