Tilting modules over almost perfect domains
An associative ring \(R\) is a perfect ring if every \(R\)-module has a projective cover. The ring \(R\) is an almost perfect ring if for every non-zero ideal \(I\) of \(R\), the ring \(R/I\) is a perfect ring. The paper under review classifies tilting modules over almost perfect domains, and cotilting modules over almost perfect Noetherian domains. Reviewer's comment: In the paper compactly packed and coprimely packed notions are used as if they are synonymous, and they are not, the later is a generalization of the former, the needed notion throughout the paper is ``coprimely packed''.
