Enumerating Toric-Colorable Seeds of Picard Number Five via Binary Matroids

Suyoung Choi, Mathieu Vallée

We introduce a binary matroid framework for the enumeration of mod $2$ toric-colorable seeds of fixed Picard number. Working with binary matroids up to isomorphism, we organize the…

Power set operads

Mathieu Vallée

We introduce a systematic method for constructing set-theoretic operads via iterated application of the power set functor, and use it to uncover a hierarchy connecting several clas…

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…
