In Boolean algebra, Poretsky's law of forms shows that the single Boolean equation f ( X ) = 0 {\displaystyle f(X)=0} is equivalent to g ( X ) = h ( X ) {\displaystyle g(X)=h(X)} if and only if g = f ⊕ h {\displaystyle g=f\oplus h} , where ⊕ {\displaystyle \oplus } represents exclusive or. The law of forms was discovered by Platon Poretsky.
