| Dec 13, 2019 at 14:59 | comment | added | Igor Belegradek | I am about to put your answer to some use, and having trouble locating where Haefliger shows in "Differential embeddings of $S^n$ in $S^{n+2}$" that the square in the beginning of your answer is homotopy Cartesian. Could you point me to the right place? I see an equivalent statement in theorem 1.11 of "Block bundles III" by Rourke-Sanderson. | |
