Introduction to Quantum ElectrodynamicsPeter Pre snajderThese are lecture notes devoted to introductory chapters of QuantumElectrodynamics (QED). The notes consist of two chapters:1. The Dirac field and the relativistic invariance- The Lorentz transformations and relativistic fields- The Dirac equation and its solutions, polarization sums- Dirac field quantization, field energy and momentum, charge- Fermions, the Dirac field propagator2. Quantum Electrodynamics and Feynman rules- QED equations of motion, Gauss law, Coulomb gauge- Free transversal electromagnetic field and its quantization- The interaction picture and the perturbation theory- Self-interacting scalar field, Feynman rules- QED in Coulomb gauge, gauge invariance- The relativisti
