... satisfiability problem for CNF formulas of propositional logic can be reduced to the consistency (or satisfia- bility) problem for formulas in FML. Thus, the consistency problem for formulas in FML is ... disjoint. The formal equivalences given in Figure 4 al- low us to transform any satisfiable formula into its disjunctive normal form, or to TOP if it is not satisfiable. The...
