Apr 11, 2016 at 17:51 | comment | added | Vidit Nanda | If there are no zigzag paths of the form $$ c > y_0 < x_0 > y_1 < x_1 > \cdots > y_k < x_k > c' $$ where $c$ and $c'$ are critical $7$ and $5$-dimensional simplices while $(y_\bullet < x_\bullet)$ lie in $\mathcal{M}$, then you definitely have homotopy equivalence with the wedge of spheres. Just be careful that all $>$ signs in the paths indicate "face of", not just "codimension 1 face" as in Forman's description. This will follow either from Liviu's answer or mine. | |
