Morita invariants of semirings related to a Morita context

摘要

The main purpose of the paper is to consider two Morita equivalent semirings R and S via Morita context ?R,S,RPS,SQR,??,?? instead of considering them via the equivalence of the resulting semimodule categories and then to investigate various Morita invariants related to each of the pairs R,S; R,P; R,Q; S,Q, etc.
