Spacetime Metrics from Gauge Potentials
نویسنده
چکیده
I present an approach to gravity in which the spacetime metric is constructed from a non-Abelian gauge potential with values in the Lie algebra of the group U(2) (or the Lie algebra of quaternions). If the curvature of this potential vanishes, the metric reduces to a canonical curved background form reminiscent of the Friedmann S cosmological metric.

Green Functions For Wave Propagation on a 5D manifold and the Associated Gauge Fields Generated by a Uniformly Moving Point Source
Gauge fields associated with the manifestly covariant dynamics of particles in (3, 1) spacetime are five-dimensional. We provide solutions of the classical 5D gauge field equations in both (4, 1) and (3, 2) flat spacetime metrics for the simple example of a uniformly moving point source. Green functions for the 5D field equations are obtained, which are consistent with the solutions for uniform...
متن کاملGauge Symmetries of the N=2 String
We study the underlying gauge symmetry algebra of the N = 2 string, which is broken down to a subalgebra in any spacetime background. For given toroidal backgrounds, the unbroken gauge symmetries (corresponding to holomorphic and antiholomorphic worldsheet currents) generate area-preserving diffeomorphism algebras of null 2-tori. A minimal Lie algebraic closure containing all the gauge symmetri...
متن کاملNavigation of Spacetime Ships in Unified Gravitational and Electromagnetic Waves
On the basis of a “local” principle of equivalence of general relativity, we consider a navigation in a kind of “4D-ocean” involving measurements of conformally invariant physical properties only. Then, applying the Pfaff theory for PDE to a particular conformally equivariant system of differential equations, we show the dependency of any kind of function describing “spacetime waves”, with resp...
متن کاملHolography, Gauge-gravity Connection and Black Hole Entropy
The issues of holography and possible links with gauge theories in spacetime physics is discussed, in an approach quite distinct from the more restricted AdSCFT correspondence. A particular notion of holography in the context of black hole thermodynamics is derived (rather than conjectured) from rather elementary considerations, which also leads to a criterion of thermal stability of radiant bl...
متن کاملSUq(n) Gauge Theory
A field theory with local transformations belonging to the quantum group SUq(n) is defined on a classical spacetime. Gauge transformations for the potentials are given which lead to the appropriate quantum-group transformations for field strengths and covariant derivatives, and gaugeinvariant commutation relations are identified.
