Non-Polynomial Lagrangian Theories
Part of the Acta Physica Austriaca book series (FEWBODY, volume 7/1970)
Barring lepton electrodynamics, most Lagrangians of physical interest are “non-renormalizable”, the apparent non-renormalizability arising either from their non-polynomial nature or from higher spins.

- 7).While this was being printed, Dr. 0. V. Steinmann (Zürich) has sent a preprint which shows that, for nonpolynomial theories, the scattering matrix exists in an axiomatic formulation and also that the LSZ reduction procedure can be carried through even though, for rational non-polynomial theories, strict local commutativity may possibly not hold. It appears that the quiet revolution which has been taking place with non-polynomial physics may acquire respectability yet.Google Scholar
