Deformation quantization generates all multiple zeta values (2409.18450v1)

Abstract: Banks--Panzer--Pym have shown that the volume integrals appearing in Kontsevich's deformation quantization formula always evaluate to integer-linear combinations of multiple zeta values (MZVs). We prove a sort of converse, which they conjectured in their work, namely that with the logarithmic propagator: (1) the coefficients associated to the graphs appearing at order $\hbar^n$ in the quantization formula generate the Q-vector space of weight-$n$ MZVs, and (2) the set of all coefficients generates the Z-module of MZVs. In order to prove this result, we develop a new technique for integrating Kontsevich graphs using polylogarithms and apply it to an infinite subset of Kontsevich graphs. Then, using the binary string representation of MZVs and the Lyndon word decomposition of binary strings, we show that this subset of graphs generates all MZVs.
