We discuss the structure of perturbative one-loop beta functions in higher-derivative gauge theories, which are quadratic in the field strengths. The action of these theories contains arbitrary integer powers n of the gauge-covariant analogue of the d’Alembert operator. We pay special attention to the discontinuities found for UV-divergences in the cases of n = 0 and n = 1. They are explained by mathematical properties of the derivation of perturbative vertices and the various usage of finite sum symbols. We also give examples of the derivation of a 3-vertex
