What is "mv-algebra"

In abstract algebra, a branch of pure mathematics, an MV-algebra is an algebraic structure with a binary operation  ⊕ , a unary operation ¬, and the constant 0, satisfying certain axioms. MV-algebras are the algebraic semantics of Łukasiewicz logic; the letters MV refer to the many-valued logic of Łukasiewicz. MV-algebras coincide with the class of bounded commutative BCK algebras.
