The structure of Sally modules of rank one

arXiv:0710.1178

Abstract

A complete structure theorem of Sally modules of $\fkm$-primary ideals in a Cohen-Macaulay local ring $(A, \m)$ satisfying the equality $\e_1(I)=\e_0(I)-\ell_A(A/I)+1$ is given, where $\e_0(I)$ and $\e_1(I)$ denote the first two Hilbert coefficients of .
