Please teach me this:
Can we demontrate the convergence of perturbation series of quantum field theory(Feymann
diagrams) after making the renormalizing procedure? If we can't demontrate that,why we still consider the perturbative method using in quantum field theory being useful and believable theory?
Thank you very much in advance.
