Ефективна дія у квантовій теорії поля

Learn about effective action in quantum field theory through this 57-minute physics seminar from OpenBITP mathphys series. Explore the definitions and properties of effective action, understand the expressions for correlators through effective action, and discover methods for calculating effective action using path integrals. Delivered in Ukrainian by Serhii Kutnii at the Bogolyubov Institute for Theoretical Physics, this advanced theoretical physics lecture provides deep insights into fundamental quantum field theory concepts.
