Direct sums of injective semimodules and direct products of projective semimodules over semirings

Il'in S. (2010)

We prove that if the direct sum of a family of semimodules over a semiring S is an injective semimodule or if the direct product of a family of semimodules over S is a projective semimodule, then the cardinality of the ...
On semirings all of whose semimodules have injective envelopes
