Yang–Mills equations and gravity
There is remarkable relation between self-dual Yang–Mills and self-dual Einstein gravity in four Euclidean dimensions. Motivated by this we investigate the Spin(7) and G2 invariant self-dual Yang–Mills equations in eight and seven Euclidean dimensions and search for their possible analogs in gravitational theories. The reduction of the self-dual Yang– Mills equations to one dimension results in...
متن کاملYang-Mills, Gravity, and 2D String Symmetries
In this work we use constructs from the dual space of the semi-direct product of the Virasoro algebra and the affine Lie algebra of a circle to write a theory of gravitation which survives in any dimension, yet takes its origins in the symmetries of string theory. The dual space of the algebra provides a natural residual symmetries left by gauge fixing and Gauss law constraints for a field theo...
متن کاملYang–Mills vacuum structure and quantum gravity
Using renormalization group methods, we calculate the derivative expansion of the effective Lagrangian for a covariantly constant gauge field in curved spacetime. Curvature affects the vacuum; in particular it could induce phase transitions between different vacua. We also consider the effect of quantum fluctuations of the metric, in the context of a renormalizable R theory. In this case the cr...
متن کاملYang-Mills origin of gravitational symmetries.
By regarding gravity as the convolution of left and right Yang-Mills theories together with a spectator scalar field in the biadjoint representation, we derive in linearized approximation, the gravitational symmetries of general covariance, p-form gauge invariance, local Lorentz invariance, and local supersymmetry from the flat space Yang-Mills symmetries of local gauge invariance and global su...
متن کاملGravitational Instability of Yang-Mills Cosmologies
The gravitational instability of Yang-Mills cosmologies is numerically studied with the hamiltonian formulation of the spherically symmetric Einstein-Yang-Mills equations with SU(2) gauge group. On the short term, the expansion dilutes the energy densities of the YangMills fluctuations due to their conformal invariance. In this early regime, the gauge potentials appear oscillating quietly in an...
