Solutions to einstein field equation
WebGeneralizations of Einstein's field equations in general relativity are derived by considering variational principles in which the components of an ennuple, or tetrad, are the quantities which undergo variation. The conservation law for the field equations is established and the weak field approximations discussed. The equations are solved by the method developed … WebApr 11, 2024 · The gravity part of the field equations is not affected by the electromagnetic Chern–Simons term and it only provides an effective potential to the equation of motion for the scalar field. When we pick the coupling constant, electric charge, and magnetic charge appropriately, the dyonic RN black hole will become unstable and there will exist …
