| Nov 8, 2011 at 17:12 | comment | added | Veen | Well, exactly this is what appears in the books and what I don't fully understand, even not in terms of modules. Above all, why is $i^*L'$ isomorphic to $L$? | |
| Nov 8, 2011 at 16:28 | comment | added | Mike Skirvin | A short exact sequence $0 \to L \to M \to L \to 0$ enables you to give $M$ the structure of a module over $X'$. You just need to be able to say how $\epsilon$ acts on $M$. Composing the projection $M \to L$ with the inclusion $L \to M$ tells you how $\epsilon$ acts. | |
