We introduce a new class of extension rings called thegeneralized Malcev-Neumann series ring R((S;σ;τ))with coefficients in a ringRand exponents in a strictly ordered monoidSwhich extends the usual construction of Malcev-Neumann series rings. Ouyang et al. in 2014 introduced the modules with the Beachy-Blair condition as follows: A rightR-module satisfies the right Beachy-Blair condition if each of its faithful submodules is cofaithful. In this paper, we study the relationship between the right Beachy-Blair condition of a rightR-moduleMRand its Malcev-Neumann series module extensionMSR((S;σ;τ)).
