Learn the fundamental concepts of Feynman integrals and integration by parts identities in this comprehensive lecture delivered by Lorenzo Tancredi at the Erwin Schrödinger International Institute for Mathematics and Physics. Explore the mathematical foundations of Feynman integrals, which are essential tools in quantum field theory for calculating scattering amplitudes and other physical processes. Discover how integration by parts identities serve as powerful techniques for simplifying and evaluating complex multi-loop integrals that arise in particle physics calculations. Master the systematic approaches used to reduce complicated integral expressions to simpler forms, enabling more efficient computational methods in theoretical physics. Gain insights into the algebraic structures underlying these mathematical tools and their applications in modern amplitude calculations. This lecture forms part of the thematic programme on "Amplitudes and Algebraic Geometry," providing essential background for understanding the intersection between advanced mathematics and theoretical physics in the context of particle interactions and quantum field theory computations.
