• Extended Rees algebra
• Local cohomology

The purpose of the paper is to study the annihilators of local cohomology of the extended Rees rings. We will prove that if (A, m) is a noetherian local ring with infinite residue field, and a is a uniform local cohomological annihilator of A, then there is an integer n such that (at)(n) is a uniform local cohomological annihilator of the extended Rees ring A[t, t(-1) I] for any m-primary ideal I of A.
