algebraic quantum field theory (perturbative, on curved spacetimes, homotopical) quantum mechanical system, quantum probability interacting field quantization The Lagrangian field theory obtained by adding the Lagrangian densities for D=3 Yang-Mills theory and of Chern-Simons theory, defined on the same gauge field/connection is 3D Yang-Mills-Chern-Simons theory (YMCS). For abelian gauge group this reduces to Maxwell-Chern-Simons theory (MCS). On ordinary Yang-Mills theory (YM): Maxwell...
