摘要
In this paper, Maths injective modules are introduced and studied. It is shown that every R-module has a (special) Maths injective preenvelope over any ring R and every right R-module has a Maths injective envelope when R is a right Noetherian ring. Moreover, it is shown that every right R-module has an F-perpendicular to 1-envelope when R is a right Noetherian ring and F is a class of injective right R-modules.
