On products of modules in a topos
Published online by Cambridge University Press: 09 April 2009
Abstract
In an elementary topos if R is a ring and X is a decidable object then there exists a canonical homomorphism from the coproduct of an X-family of R-modules to the product of the same family. In this paper it is shown that this homomorphisms is a monomorphism.
