On the product of semigroup valued measures. (English) Zbl 0917.28011
A version of Alexandroff’s theorem for measures defined on a ring and with values in a \(\sigma \)-complete commutative semigroup is proved. This result is applied to the existence of a product measure with values in a \(\sigma \)-distributive \(\ell \)-ring as well as to the existence of a joint observable on MV-algebras.
