| Feb 8, 2016 at 12:49 | comment | added | André Henriques | In this case, there's not much difference between an image of embedding and an embedding. After fixing base points, you can always take the constant-speed parametrization of an embedded curve. Does what I say make sense, or did I overlook something basic? | |

| Feb 8, 2016 at 7:59 | comment | added | Oscar Randal-Williams | I don't understand this example. What is the path of embeddings (and not just the path of images of embeddings)? | |
| Feb 8, 2016 at 6:58 | comment | added | s k | I assumed the embeddings are proper and the spaces are smooth. | |
| Feb 8, 2016 at 6:46 | comment | added | s k | Thanks André, but I have sketched a proof that the induced map is a Kan fibration using Siebenmann's isotopy extension theorem. How far can that be right? | |
