Bounded Modules

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
Let R be a commutative ring with identity, and let M be a unitary (left) R- modul e. The ideal annRM  = {r E R;rm  = 0 V  mE M} plays a central   role  in  our  work.

On P-coherent endomorphism rings

open access: yesProceedings Mathematical Sciences, 2008
Let \(M_R\) be a right \(R\)-module and \(S\) the endomorphism ring of \(M_R\). The \(P\)-coherence of ring \(S\) is studied (i.e. when every principal right ideal of \(S\) is finitely presented). The following conditions are equivalent: (1) \(S\) is a right \(P\)-coherent ring; (2) Every cyclically \(M\)-copresented right \(R\)-module has an \(\text ...

Comprehensive Analysis and Implementation of Isogeny-Based Hash Functions

open access: yesIEEE Access
This paper analyzes the security and performance of the isogeny-based hash functions. The isogeny-based hash function was first proposed by Charles, Goren, and Lauter, and is referred to as the CGL hash function.

Endomorphism algebras over large domains [PDF]

open access: yes, 1998
The paper deals with realizations of R-algebras A as endomorphism algebras End G ≅ A of suitable R-modules G over a commutative ring R. We are mainly interested in the case of R having "many prime ideals", such as R = ℝ[x], the ring of real polynomials ...

Computational aspects of the endomorphism ring of the Jacobian of a curve of genus two [PDF]

open access: yes, 2005
Building on a method of Zarhin, we determine the tensor of the endomorphism ring of the Jacobian over the field of two elements in the case of a genus two curve defined as a double cover over the projective line by an irreducible polynomial of degree ...
