Quantum Field Theory: Renormalization

This lecture covers the topic of Algebraic Quantum Field Theory (AQFT) with a focus on renormalization in the context of two-loop diagrams. The instructor discusses the process of wave function renormalization and the calculation of loop diagrams, emphasizing the importance of understanding the renormalization group. The lecture also delves into the concept of renormalization scale and the significance of two-loop diagrams in quantum field theory. Various terms and equations related to renormalization are explained, providing a comprehensive overview of the topic.
