WebbExample 2.8. A ring R is called a V -ring if every simple left (resp. right) R-module is injective. For such a ring R, any simple left R-module S coincides with its injective hull E(S) = S and is therefore cyclic. Thus V -rings provide a large class of hypersimple rings. It is well-known, that a commutative ring is a V-ring if Webb3 mars 2024 · Injective Group Homomorphism that does not have Inverse Homomorphism Problem 443 Let A = B = Z be the additive group of integers.

WebbInjection Let f : A → B be a function from the domain A to the codomain B. The function f is called injective (or one-to-one) if it maps distinct elements of A to distinct elements of B. In other words, for every element y in the codomain B there exists at most one preimage in the domain A: Figure 1.
