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. Han Yan; Physics. 2024; In this work we reason that there is a universal picture for several different holographic toy model constructions, and a gravity-like bulk field theory that gives rise it.
Web12 Apr 2024 · Abstract. The generalized SU (2) Proca theory is a vector-tensor modified gravity theory where the action is invariant under both diffeomorphisms and global internal transformations of the SU (2) group. This work constitutes the first approach to investigate the physical properties of the theory at astrophysical scales.
