Torsion Obstruction for Conclusive Posets

Combinatorics 2026-01-26 v1

Abstract

We give a counterexample to a conjecture made by Cigler, Jerman and Wojciechowski stating that all posets are conclusive. We also provide combinatorial characterizations for conclusiveness of finite posets and the existence of outer derivations.
