Abstract
We introduce a new algebraic structure
called Gödel–MV-algebra (GMV-algebra) such that
-
\((A, \otimes , \oplus , *, 0, 1)\) is MV-algebra;
-
\((A,\vee , \wedge ,\rightharpoonup , 0, 1)\) is a Gödel algebra (i. e. Heyting algebra satisfying the identity \((x \rightharpoonup y ) \vee (y \rightharpoonup x ) =1\)).
It is shown that the lattice of congruences of a GMV -algebra \((A, \otimes , \oplus , *, \rightharpoonup , 0, 1)\) is isomorphic to the lattice of Skolem filters (i. e. special type of MV-filters) of the MV-algebra \((A, \otimes , \oplus , *, 0, 1)\). Any GMV-algebra is bi-Heyting algebra. Any chain GMV-algebra is simple, and any GMV-algebra is semi-simple. Finitely generated GMV-algebras are described, and finitely generated finitely presented GMV-algebras are characterized. The algebraic counterpart of axiomatically presented GMV-logic is GMV-algebras .
