On commutative endomorphism rings [PDF]

open access: yesPacific Journal of Mathematics, 1970
This note deals with a finitely generated faithful module E over a commutative semi-prime noetherian ring R, with commutative endomorphism ring HomJ2(Er, E) = Ω(E). It is shown that E is identifiable to an ideal of R whenever Ω(E) lacks nilpotent elements; a class of examples with Ω(E) commutative but not semi-prime is discussed.

Centers of Categorified Endomorphism Rings [PDF]

open access: yesAlgebras and Representation Theory, 2022
We prove that for a large class of well-behaved cocomplete categories $\mathcal C$ the weak and strong Drinfeld centers of the monoidal category $\mathcal{E}$ of cocontinuous endofunctors of $\mathcal{C}$ coincide. This generalizes similar results in the literature, where $\mathcal{C}$ is the category of modules over a ring $A$ and hence $\mathcal{E ...

A KIND OF F-INVERSE SPLIT MODULES [PDF]

open access: yesJournal of Algebraic Systems, 2020
Let M be a right module over a ring R. In this manuscript, we shall study on a special case of F-inverse split modules where F is a fully invariant submodule of M introduced in [12].

Finite valuated groups as modules over their endomorphism ring [PDF]

open access: yes, 2017
This paper discusses the structure of a finite valuated p-group when viewed as a module over its endomorphism ring. A category equivalence between full subcategories of the category of valuated p-groups and the category of right modules over the ...

The supersingular endomorphism ring problem given one endomorphism [PDF]

open access: yes
Given a supersingular elliptic curve E and a non-scalar endomorphism α of E, we prove that the endomorphism ring of E can be computed in classical time about disc(Z[α])^1/4, and in quantum subexponential time, assuming the generalised Riemann hypothesis.

The supersingular endomorphism ring problem given one endomorphism [PDF]

open access: yes, 2023
Given a supersingular elliptic curve E and a non-scalar endomorphism $\alpha$ of E, we prove that the endomorphism ring of E can be computed in classical time about disc(Z[$\alpha$])^1/4 , and in quantum subexponential time, assuming the generalised ...

Isomorphism Between Endomorphism Rings of Modules Over A Semisimple Ring [PDF]

open access: yes, 2020
Our question is what ring R which all modules over R are determined, up to isomorphism, by their endomorphism rings? Examples of this ring are division ring and simple Artinian ring. Any semi simple ring does not satisfy this property.

Rings all of whose additive group endomorphisms are left multiplications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Motivated by Cauchy's functional equation f(x+y)=f(x)+f(y), we study in §1 special rings, namely, rings for which every endomorphism f of their additive group is of the form f(x)≡ax. In §2 we generalize to R algebras (R a fixed commutative ring) and give
