The DeWitt Equation in Quantum Field Theory [PDF]
Parikshit Dutta, Krzysztof A. Meissner, Hermann NicolaiWe take a new look at the DeWitt equation, a defining equation for the effective action functional in quantum field theory. We present a formal solution to this equation, and discuss the equation in various contexts, and in particular for models where it can be made completely well defined, such as the Wess-Zumino model in two dimensions.View original: http://arxiv.org/abs/1303.3497
