We use the theory based on a gravitational gauge group (Wu's model) to obtain a spherical symmetric solution of the Geld equations for the gravitational potential on a Minkowski spacetime. The gauge group, the gauge covariant derivative, the strength tensor of the gauge Held, the gauge invariant Lagrangean with the cosmological constant, the Geld equations of the gauge potentials with a gravitational energy-momentum tensor as well as with a tensor of the Geld of a point like source are determined. Finally, a Reissner-Nordstrom-de Sitter-type metric on the gauge group space is obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
