My review “Axiomatic classical (prequantum) field theory”



G. Sardanashvily, Axiomatic classical (prequantum) field theory. Jet formalism
arXiv:hep-th/0612182
  
Abstract. In contrast with QFT, classical eld theory can be formulated in a strict mathematical way if one denes even classical elds as sections of smooth ber bundles. Formalism of jet manifolds provides the conventional language of dynamic systems (nonlinear dierential equations and operators) on ber bundles. Lagrangian theory on ber bundles is algebraically formulated in terms of the variational bicomplex of exterior forms on jet manifolds where the Euler–Lagrange operator is present as a coboundary operator. This formulation is generalized to Lagrangian theory of even and odd elds on graded manifolds. Cohomology of the variational bicomplex provides a solution of the global inverse problem of the calculus of variations, states the rst variational formula and Noether’s rst theorem in a very general setting of  supersymmetries depending on higher-order derivatives of elds. A theorem on the Koszul–Tate complex of reducible Noether identities and Noether’s inverse second theorem extend an original eld theory to prequantum eld-antield BRST theory. Particular eld models, jet techniques and some quantum outcomes are discussed.

Victor Ambartsumian and Dmitri Ivanenko in history of Quantum Field Theory

WikipediA article "History of Quantum Field Theory" says the following.


“… Of great importance are the studies of Soviet physicists, Viktor Ambartsumian and Dmitri Ivanenko, in particular the Ambarzumian - Ivanenko hypothesis of creation of massive particles (published in 1930) which is the cornerstone of the contemporary quantum field theory. The idea is that not only the quanta of the electromagnetic field, photons, but also other particles (including particles having nonzero rest mass) may be born and disappear as a result of their interaction with other particles. This idea of Ambartsumian and Ivanenko formed the basis of modern quantum field theory and theory of elementary particles.”
