Lecture
This lecture covers advanced topics in Quantum Field Theory, including representations of the Poincare group, LSZ approach to S-matrix, path integral approach, renormalization, quantized gauge theories, infrared effects, and the construction of unitary irreps. The lecture also delves into the Hilbert space, Fock space, Noether charges, and single particle states. The instructor discusses the generators, exponential map, and the Casimirs in ISO(3,1). The lecture concludes with the induced representation method and the construction of irreps over Fock space.
