| Jun 14, 2017 at 20:30 | comment | added | Mohan | If $\Lambda$ is a finitely generated $R$-module, this is correct. If you merely assume that it is just a finitely generated $R$-algebra (as you state in the question), this is false in general. | |
| Jun 14, 2017 at 18:20 | comment | added | Homa81 | $\Lambda$ is finitely genreated as an $R$-module. In fact, $\Lambda$ is a noether $R$-algebra. | |
| Jun 14, 2017 at 18:06 | comment | added | Will Sawin | Is $\Gamma$ finitely generated as a module or an algebra? If an algebra, what if $R= k[x], \Gamma = k[x,x^{-1}]$? | |
