Subdirect product of PS-rings need not be PS
Published online by Cambridge University Press: 17 April 2009
Abstract
An associative ring R with identity is called a PS-ring if soc(RR) is projective. We construct a non- PS-ring R which is a subdirect product of two PS-rings, thus answering a question of Nicholson and Watters in the negative.
