Apr 29, 2014 at 16:46 | comment | added | Jeremy Rickard | @FernandoMuro: Ah, right. So "conjugate by an element of $G$" versus "conjugate by an element of $\operatorname{Aut}(E)$". Yes, I guess both are reasonable interpretations of the question. | |
Apr 29, 2014 at 16:40 | comment | added | Fernando Muro | @JeremyRickard Thanks, I thought that 'conjugated' meant twisted by inner automorphisms. | |
Apr 29, 2014 at 16:36 | comment | added | Jeremy Rickard | @FernandoMuro: My understanding of the question may be different to yours, but aren't they conjugate by $x\mapsto -x$? But what about $\mathbb{Z}$ acting on a copy of $\mathbb{R}$ with little blobs around each integer, by $x\mapsto x+n$ and $x\mapsto x+2n$? | |

Apr 29, 2014 at 16:25 | comment | added | Fernando Muro | I may be misunderstanding the question (namely, the use of 'conjugated'), but whay about $\mathbb Z$ acting on $\mathbb R$ by $x\circ n=x+n$ and $x\bullet n=x-n$? | |
