Involution Operation Definition/Meaning:

Any unary operation /that satisfies the law

ƒ(ƒ(a)) = a

for all a in the domain of ƒ The law is known as the involution law. It is satisfied by the elements of a Boolean algebra where the unary function is the process of taking a complement. Taking complements of sets and negation in its different forms also satisfy the law, as does the principle of duality as it applies in Boolean algebras.
