On a cancellation rule for subdirect products of lattice ordered groups and of GMV-algebras
Ján Jakubík · Mathematica Slovaca · 2007
Abstract The notion of internal subdirect decomposition can be defined in each variety of algebras. In the present note we prove the validity of a cancellation rule concerning such decompositions for lattice ordered groups and for GMV-algebras. For the case of groups, this cancellation rule fails to be valid.
