Self-Dual Theory

Type: Concept

As of November 2026, Self-Dual Theory has been mentioned in one podcast episode on Simons Foundation (Jan 2026). Discussed as a sector of Yang-Mills theory with deep connections to instantons.

In physics and mathematics, and especially differential geometry and gauge theory, the Yang–Mills equations are a system of partial differential equations for a connection on a vector bundle or principal bundle. They arise in physics as the Euler–Lagrange equations of the Yang–Mills action functional. They have also found significant use in mathematics.
