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 … Zobacz więcej 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 … Zobacz więcej 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 … Zobacz więcej 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 … Zobacz więcej • Gauge principle • Aharonov–Bohm effect • Coulomb gauge Zobacz więcej 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 … Zobacz więcej 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 … Zobacz więcej 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 … Zobacz więcej WitrynaSince $\Lambda$ is a constant, however, this gauge transformation must be the same at all points in space-time; it is a global gauge transformation. ... $\Lambda(x^\mu)$. This is called a local gauge … Witrynanotion of gauge transformation will be given and nally a connection on a vector bundle will be de ned, an object to be recognised as a gauge potential. 1 Introduction A … sapphire 850 repairs
