The relative join operad and polyhedral products

Mathieu Vallée

An inclusion of nonvoid simplicial complexes induces an arrow of polyhedral products. Applying Ayzenberg's polyhedral join to both complexes gives a symmetric relative join operad.…

Toric wedge induction and toric lifting property for piecewise linear spheres with a few vertices

Suyoung Choi, Hyeontae Jang, Mathieu Vallée

Let $K$ be an $(n - 1)$ -dimensional piecewise linear sphere on $[m]$ , where $m \leq n + 4$ . There are a canonical action of $m$ -dimensional torus $T^{m}$ on the moment-angle complex $\mat…
