##### 1. A SHORT PROOF OF A RESULT OF NAGEL

Let $(R,fm)$ be a Gorenstein local ring and$M,N$ be two finitely generated modules over $R$. Nagel proved that if $M$ and $N$ are inthe same even liaison class, thenone has $H^i_{fm}(M)cong H^i_{fm}(N)$ for all \$iIn this paper, we provide a short proof to this result.  Read More
