| Nov 29, 2009 at 18:23 | comment | added | Leonid Positselski | These two assertions: "R_p is then an algebra over Z/p." and "If R is local with maximal ideal m, it is an algebra over the finite field F=R/m." -- are obviously wrong, as applied to finite rings, in general. Take R = R_p = R_m = Z/p^nZ, n>1. | |
