Results in Quantum Field Theories, such as anomalous magnetic moments, anomalous dimensions or periods of Feynman graphs are very much constrained by principles that are expressed in terms of a coaction that acts on these quantities. I will show how these phenomena arise directly from the Baxter equation describing the anomalous dimensions in a four-dimensional integrable scalar model.
