| Jun 28 at 11:30 | comment | added | Dominic van der Zypen | I have tried to make the title catchier. - @JukkaKohonen : $\varphi(e_1)= \text{im}(\varphi|_{e_1})$, so $\varphi(e_1)$ is the image of $e_1\subseteq V_1$ under $\varphi$. This is a subset of $V_2$. Now $E_2$ is a collection of subsets of $V_2$. Whence the requirement $\varphi(e_1)\in E_2$. Does that make sense? | |
| Jun 28 at 7:47 | comment | added | Jukka Kohonen | I think the isomorphism definition needs some work. If $\varphi$ is from $V_1$ then $\varphi(e_1)$ does not automatically make sense for $e_1 \in E_1$. | |
