review text: The authors derives the short distance expansion for a product of two (arbitrary) composite operators in the framework of the perturbative Euclidean massive \(\phi^ 4_ 4\) theory (Theorems 9 and 10) by using an extension of the differential flow equation method to Green functions with bilocal insertions, for whicha set of generalized Zimmermann identities and Löwenstein rules are also established.
