The 11-loop graph cohomology

Quantum Algebra 2025-08-20 v1 Algebraic Topology

Abstract

We compute the Kontsevich graph cohomology in loop order 11, and for some degrees in higher loop order. We apply our results to discuss a conjecture of F. Brown, providing a counterexample to a strong version of the conjecture.
