In theoretical physics, the AGT correspondence is a relationship between Liouville field theory on a punctured Riemann surface and a certain four-dimensional SU(2) gauge theory obtained by compactifying the 6D (2,0) superconformal field theory on the surface.
The relationship was discovered by Luis Alday, Davide Gaiotto, and Yuji Tachikawa in 2009.
[1] It was soon extended to a more general relationship between AN-1 Toda field theory and SU(N) gauge theories.
[2] The idea of the AGT correspondence has also been extended to describe relationships between three-dimensional theories.
