DENUMERABLE PRODUCT SPACES OF PSEUDOQUOTIENTS I

September 25th, 2019, 8:04AM

A space of pseudoquotients ß(X,G) is defined as the set of equivalence classes of pairs (x, g), where x X, an arbitrary non-empty set, and g G, a commutative semigroup acting on X such that (x, g)~(y, h) if hx = gy. In this paper, we shall construct the pseudoquotient space ß(ΠXi,ΠGi) where X is replaced by a cartesian product of countably infinite non-empty sets Xi and G by a direct product denumerable commutative semigroups Gi, i I an indexing set, such that ΠGi acts injectively on ΠXi.
