    I have further expanded the Idea-section and the list of commented references at perturbative quantum field theory.

    (Not proof-read yet, need to run to catch a train.)

    In order to make the pointer to references on the original informal formulation of the theory more robust and useful, I am starting a collective category:reference entry titled

    The idea is to collect the relevant original articles of these four authors, together with reviews and historical accounts there in one place.

    This is not done yet. I have just filled in some bare minimum. Maybe somebody here feels inspired to add more. Otherwise I come back to it later.

    added also the following pointers (all in the section here on non-convergence of the perturbation series):

    added pointer (here) to

    for review of Dyson’s argument that the perturbation series of interesting QFTs has vanishing radius of convergence

    added to the Idea-section (here) a graphics meant to illustrate the small (really: infinitesimal) region in parameter space that is described by perturbative QFT.

    (This is the same graphics I had also added to non-perturbative effect, as announced there)

    have added pointers to a few more of the non-rigorous but standard textbooks (Bjorken & Drell, Peskin & Schroeder, Weinberg)
