Feynman's technique of integration

WebFor ordinary integrals, it's almost always easier to use contour techniques. The trouble with differentiating under the internal sign is that you have to guess what generalized function will help with solving the integral. … WebIn these lecture notes we give an introduction to the very wide and active eld of Feynman integrals and the techniques used to evaluate them. We assume familiarity with the basic ideas of perturbative quantum eld theory and Feynman diagrams, but introduce all of the concepts that are used in the example calculations below. In large parts these ...
