Introduction to Gauge Theory

Explore the fundamental concepts of gauge theory through this comprehensive lecture series delivered at the Park City Mathematics Institute. Delve into the mathematical foundations that underpin modern theoretical physics, including the geometric and topological aspects of gauge fields. Learn about principal bundles, connections, curvature, and their applications in both mathematics and physics. Examine the Yang-Mills equations and their significance in quantum field theory. Study the relationship between gauge theory and differential geometry, including how gauge transformations preserve physical observables. Investigate instantons, monopoles, and other topological solitons that arise naturally in gauge theories. Understand the role of gauge theory in the Standard Model of particle physics and its connections to knot theory and low-dimensional topology. Master the techniques for analyzing gauge-theoretic moduli spaces and their compactifications. Discover applications to four-manifold topology, including Donaldson theory and Seiberg-Witten theory, which have revolutionized our understanding of smooth four-dimensional manifolds.
