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 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…
