The Mathematics of TQFTs and Defects

Delve into the intricate world of Topological Quantum Field Theories (TQFTs) and defects in this comprehensive 5-hour 17-minute conference talk by C. Teleman from Berkeley University. Explore the mathematical foundations underpinning these complex concepts as part of the "Categorical Symmetries in Quantum Field Theory" conference and school. Gain insights into the advanced mathematical techniques used to describe and analyze TQFTs, and understand the role of defects in these theories. Examine the intersection of category theory, topology, and quantum physics, and discover how these fields converge to create a deeper understanding of fundamental physical phenomena.
