Finster, Felix and Tolksdorf, Jürgen (2012) Bosonic loop diagrams as perturbative solutions of the classical field equations in 4-theory. Preprintreihe der Fakultät Mathematik 2/2012, Working Paper.
Solutions of the classical �4-theory in Minkowski space-time are analyzed in a perturbation expansion in the nonlinearity. Using the language of Feynman diagrams, the solution of the Cauchy problem is expressed in terms of tree diagrams which involve the retarded Green’s function and have one outgoing leg. In order to obtain general tree diagrams, we set up a “classical measurement process” ...
