For logarithmically divergent one-loop lattice Feynman integrals I(p,a) , subject to mild general conditions, we prove the following expected and crucial structural result: I(p,a)=f(p)log(aM)+g(p)+h(p,M) up to terms which vanish for lattice spacing a→0 . Here p denotes collectively the external mo...
