Two-dimensional Yang–Mills theory is a gauge theory that generalizes the concept of Yang–Mills theories to two spatial dimensions. In general, Yang–Mills theories are constructed from a gauge field that transforms under a symmetry group (the gauge group), and they play a crucial role in modern theoretical physics, particularly in quantum field theory and the Standard Model of particle physics.
