Gauge Theory of Gravity
The quantum gravity is formulated based on principle of local gauge invariance. The model discussed in this paper has local gravitational gauge symmetry and gravitational field appears as gauge field. The problems on quantization and renormalization of the theory are also discussed in this paper. In leading order approximation, the gravitational gauge field theory gives out classical Newton’s t...
متن کاملGravity and Gauge Theory∗
Gauge theories are theories that are invariant under a characteristic group of gauge transformations. General relativity is invariant under transformations of the diffeomorphism group. This has prompted many philosophers and physicists to treat general relativity as a gauge theory, and diffeomorphisms as gauge transformations. I argue that this approach is misguided. The theories of three of ...
متن کاملQuantum Gauge Theory of Gravity
The quantum gravity is formulated based on principle of local gauge invariance. The model discussed in this paper has local gravitational gauge symmetry and gravitational field is represented by gauge field. In leading order approximation, it gives out classical Newton’s theory of gravity. It can also give out Einstein’s field equation with cosmological constant. For classical tests, it gives o...
متن کاملGauge Theory of Quantum Gravity
A gauge theory of quantum gravity is formulated, in which an internal, field dependent metric is introduced which non-linearly realizes the gauge fields on the non-compact group SL(2, C), while linearly realizing them on SU (2). Einstein's SL(2, C) invariant theory of gravity emerges at low energies, since the extra degrees of freedom associated with the quadratic curvature and the internal met...
متن کاملLinearized Gravity as a Gauge Theory
We discuss linearized gravity from the point of view of a gauge theory. In (3+1)dimensions our analysis allows to consider linearized gravity in the context of the MacDowell-Mansouri formalism. Our observations may be of particular interest in the strong-weak coupling duality for linearized gravity, in Randall-Sundrum brane world scenario and in Ashtekar formalism.
