gauge theory

n. Physics
Any of various theories based upon a gauge symmetry. Current fundamental theories, such as the standard model of particle physics, are gauge theories.

The apparent lack of a generic tunable parameter that allows to solve the theory perturbatively (like the electric coupling constant in electrodynamics, or the rank of the gauge group in large-N Yang-Mills theory) is arguably the single most important obstacle for generic efficient approaches to the physics of strong gravity and black holes.

of California-San Diego) investigate the global in time regularity of the Yang-Mills equations on high dimensional Minkowski space with compact matrix gauge group G.
In general, if G is a topological group, X is a space, and P [right arrow] X is a principal G-bundle, then the gauge group G (P) of the bundle is the group of G-equivariant automorphisms of P which fix X.

For historical reasons the local symmetry group is known as a gauge group (strictly of the so-called second kind - the corresponding global symmetry is a gauge symmetry of the first kind) and the hope is widely shared that all interactions, including electromagnetic, strong, weak, and even gravitational, can be derived by imposing the appropriate local gauge symmetry.

Among the topics are deformations and cohomology, the gauge group, strongly homotopy Lie algebras, and operads.
