WebMathematically, a Yang–Mills instanton is a self-dual or anti-self-dual connection in a principal bundle over a four-dimensional Riemannian manifold that plays the role of physical space-time in non-abelian gauge theory.Instantons are topologically nontrivial solutions of Yang–Mills equations that absolutely minimize the energy functional within their … In physics, a gauge theory is a type of field theory in which the Lagrangian (and hence the dynamics of the system itself) does not change (is invariant) under local transformations according to certain smooth families of operations (Lie groups). The term gauge refers to any specific mathematical … See more The earliest field theory having a gauge symmetry was Maxwell's formulation, in 1864–65, of electrodynamics ("A Dynamical Theory of the Electromagnetic Field") which stated that any vector field whose curl vanishes—and … See more Classical electromagnetism Historically, the first example of gauge symmetry discovered was classical electromagnetism. In electrostatics, one can either discuss the electric field, E, or its corresponding electric potential, V. Knowledge of one … See more Gauge theories may be quantized by specialization of methods which are applicable to any quantum field theory. However, because of the subtleties imposed by the gauge constraints (see section on Mathematical formalism, above) there are … See more • Gauge principle • Aharonov–Bohm effect • Coulomb gauge • Electroweak theory • Gauge covariant derivative See more Global and local symmetries Global symmetry In physics, the mathematical description of any physical situation usually contains excess degrees of freedom; the same physical situation is equally well described by many equivalent … See more Gauge theories are usually discussed in the language of differential geometry. Mathematically, a gauge is just a choice of a (local) section of some principal bundle. A gauge transformation is just a transformation between two such sections. Although gauge … See more A pure gauge is the set of field configurations obtained by a gauge transformation on the null-field configuration, i.e., a gauge transform of zero. So it is a particular "gauge orbit" in the field configuration's space. Thus, in the abelian … See more

WebAug 24, 2024 · The first gauge theory was Maxwell theory. Going back to the economic analogy, consider a certain bank on a certain bridge. The number of speculators moving in either side determines what the bank does to the exchange rate. The bank may run out of a particular currency if there is an imbalance in the two sets of speculators.
