Exact Results in Quantum Theory

In this seminar, we present a positive solution to the adiabatic limit problem in causal perturbative QED, as well as give a contribution to the solution of the convergence problem for the perturbative series in QED, by using white noise construction of free fields. The method is general enough to be applicable to more general causal perturbative QFT, such as Standard Model with the Higgs field.
