Abstract

The c2c_2-invariant is an arithmetic graph invariant useful for understanding Feynman periods. Brown and Schnetz conjectured that the c2c_2-invariant has a particular symmetry known as completion invariance. This paper will prove completion invariance of the c2c_2-invariant in the p=2p=2 case, extending previous work of one of us. The methods are combinatorial and enumerative involving counting certain partitions of the edges of the graph.
