| Nov 22, 2022 at 4:20 | comment | added | F Zaldivar | The action of $G$ on itself by translation is a morphism $L_g:G\rightarrow G$ (which is only a homomorphism when $g=e$ is the neutral element of $G$) and the claim that is used by Borel is that the action $L_g$ extends to the complete curve $\overline{G}$ as a morphism $L_g:\overline{G}\rightarrow G$, which again is almost never a homomorphism. | |
