Throughout this post, I consider "R-module" and "representation of R" to be the same.
Similarly, I consider "A-module" and "representation of A" to be the same.
I define of a representation of a unital ring R as an Abelian group M together with a homomorphism from R to the unital ring of endomorphisms of M.
I define of a representation of a unital associative algebra A as a vector space V together with a homomorphism from A to the unital associative algebra of endomorphisms of V.
Question:
Is it so that the notion of a representation of a unital associative algebra generalises the notion of a representation of a unital ring? I think I've heard this result, but can't find it by a Google search.
It would seem strange if it were true, since the notion of a unital ring actually generalizes the notion of a unital associative algebra.
