| Jan 7, 2021 at 17:04 | comment | added | ABB | Yes, by the natural inclusion $V_i \hookrightarrow \prod V_j$ for every $i$. | |
| Jan 7, 2021 at 16:53 | comment | added | R. van Dobben de Bruyn | What do you mean by 2? Does the embedding have the restrict to the natural inclusions $V_i \hookrightarrow \prod V_j$? It seems more natural to ask for the natural map $\bigoplus V_i \twoheadrightarrow V$ to be surjective (or use quotients instead of subobjects and dualise). | |
