With every $R$-module $M$ associate the direct limit of $\Hom_R (D, M)$ over the dense right ideals of $R$, the derived quotient module $\mathcal{D}(M)$ of $M ...
Algebraic structures such as semirings and modules have long been a fertile ground for both theoretical exploration and practical application. Semirings, generalisations of rings that typically lack ...
