| Nov 11, 2019 at 16:30 | comment | added | Student | Have you drawn some simple examples ($p=1,2$) after reading @Hatcher's answer below? I think the the consideration of $(-\times I)$ could be quite helpful. | |

| Nov 8, 2019 at 19:10 | comment | added | Akerbeltz | @CharlesRezk I already did some work in drawing some simple cases. However this didn't solve the problem. | |
| Nov 8, 2019 at 17:10 | comment | added | Charles Rezk | In particular, the formula for the boundary of the cone is just saying: the boundary of a cone is the union of the "hat" part of the cone and the "base" of the cone. | |
| Nov 8, 2019 at 17:09 | comment | added | Charles Rezk | I recommend computing $h$ for a single simplex $\sigma$ of low dimension (e.g., 0, 1, 2). This might give you a better idea of what is goin on. | |
| Nov 7, 2019 at 21:10 | comment | added | Akerbeltz | If $\mathcal{U}$ is an oper cover of a topological space $X$, $C_\bullet^\mathcal{U}(X)$ represents the chain complex of \mathcal{U}-small chains in $X$, whose elements are chains such that the image of each of its simplices is contained in some element of the cover $\mathcal{U}$. $H_p^\mathcal{U}(X)$ is just the homology of such complex. | |
| Nov 7, 2019 at 21:02 | comment | added | Arun Debray | Sorry for my confusion, but what are $C_*^{\mathcal U}(X)$ and $H_p^{\mathcal U}(X)$? I am not familiar with that notation. | |
