On endomorphism rings of local cohomology
Michael Hellus, Juergen Stueckrad
Let R be a local complete ring. For an R-module M the canonical ring map R\to End_R(M) is in general neither injective nor surjective; we show that it is bijective for every local…

Generalization of an example of Hartshorne concerning local cohomology
Michael Hellus, Juergen Stueckrad
We prove the following generalization of an example of Hartshorne: Let k be a field, n=4, R = k[[X1,...,Xn]], I = (X1,...,Xn-2)R and p\in R a prime element such that p\in(Xn-1,Xn)R…
