Abstract:
In the electromagnetic minimum coupling model, the authors study the expansion of the finite quantity function in the momenta renormalization e - e loop propagator function, and find that if they use the matrix function expansion they can approach the separation of the finite quantity function, but also can get a strictly analytic solution for one dimension integral calculation method of it. This will give an effective new way to study the question about the exact solving to the renormalization finite quantity function.
