A propositional formula is a DNF formulaMathworldPlanetmathPlanetmath, meaning Disjunctive Normal FormMathworldPlanetmath, if it is a disjunctionMathworldPlanetmath of conjunctionsMathworldPlanetmath of literalsMathworldPlanetmath (a literal is a propositional variable or its negationMathworldPlanetmath). Hence, a DNF is a formula of the form: K1K2Kn, where each Ki is of the form li1li2lim for literals lij and some m which can vary for each Ki.

Example: (xy¬z)(y¬w¬u)(xv).
