WebSU(2) gauge theory leads to some surprises: the dimensional reduction to curved space, the appearance of Higgs fields, and the reduction of the gauge group to U(l). The general methods developed in this article for constructing symmetric gauge fields lead to an understanding of these features, and we shall conclude with a reanalysis of Witten's ... khac che fiora top https://daria-b.com

WebFrom this we are able to relate the Riemann tensor, and its contractions, to the equivalent tensors in the absence of torsion. We then consider the symmetries of the Riemann tensor and the gauge theory version of the Bianchi identity. As is well known, much of the symmetry of the Riemann tensor is lost when torsion is included. http://fma.if.usp.br/~burdman/QFT2/lecture_15.pdf

Yang–Mills theories are special examples of gauge theories with a non-abelian symmetry group given by the Lagrangian with the generators of the Lie algebra, indexed by a, corresponding to the F-quantities (the curvature or field-strength form) satisfying Here, the f are structure constants of the Lie algebra (totally antisymmetric if th… Web2 Jul 2024 · Geodesic string condensation from symmetric tensor gauge theory: a unifying framework of holographic toy models.
