Minimal Prüfer-Dress rings and products of idempotent matrices
Laura Cossu, Paolo Zanardo
We investigate a special class of Prüfer domains, firstly introduced by Dress in 1965. The {\it minimal Dress ring} , of a field , is the smallest subring of that conta…

Factorizations into idempotent factors of matrices over Prüfer domains
Laura Cossu, Paolo Zanardo
A classical problem, that goes back to the 1960's, is to characterize the integral domains R satisfying the property (IDn): "every singular nxn matrix over R is a product of idempo…
