Abstract
In this paper interacting quantum elds,electron self-energy,vacuum polarization,methods
of calculating electron and photon self-energy and Wick rotation are reviewed.These self-
energy calculating methods include Pauli-Villars regularization and dimensional regular-
iztion.Electron self-energy is calculated by using Pauli-Villars regularization method while
the photon self-energy is by dimensional regularization method
