On product M V -algebras

Ján Jakubík (2002)

Czechoslovak Mathematical Journal

Similarity:

In this paper we apply the notion of the product M V -algebra in accordance with the definition given by B. Riečan. We investigate the convex embeddability of an M V -algebra into a product M V -algebra. We found sufficient conditions under which any two direct product decompositions of a product M V -algebra have isomorphic refinements.

A spectral theorem for σ MV-algebras

Sylvia Pulmannová (2005)

Kybernetika

Similarity:

MV-algebras were introduced by Chang, 1958 as algebraic bases for multi-valued logic. MV stands for “multi-valued" and MV algebras have already occupied an important place in the realm of nonstandard (mathematical) logic applied in several fields including cybernetics. In the present paper, using the Loomis–Sikorski theorem for σ -MV-algebras, we prove that, with every element a in a σ -MV algebra M , a spectral measure (i. e. an observable) Λ a : ℬ ( [ 0 , 1 ] ) → ℬ ( M ) can be associated, where ℬ ( M ) denotes the Boolean...

Isometries of generalized M V -algebras

Czechoslovak Mathematical Journal

Similarity:

In this paper we investigate the relations between isometries and direct product decompositions of generalized M V -algebras.
