Negation Normal Form - For any propositional variables p, q, and r, we have:((p_q)^(q ! To use structural induction to prove properties. Math foundations of cs jeremy johnson. A propositional formula p p is in negation normal form ( nnf) if and only if : Web a literal is an atomic formula or its negation. Web negation normal form (nnf) disjunctive normal form (dnf) conjunctive normal form (cnf) every formula of pl can be. For every literal l, the literal complementary to l, denoted l is defined as follows:
