Yang–Mills theory

“The Yang-Mills theories that are the foundation of the Standard Model in modern physics and geometry, are founded in a tradition that has explicitly mixed Maxwellian electricity and mathematics, tensors and topology, charges and fields, poles and holes, functions and spaces: Riemann (1851, 1857) and Gustav Roch (1865), Maxwell (1873), Felix Klein (1890), Hermann Weyl (1913), and W. V. D. Hodge (1940).”
