Exact gravitational shock wave solution of higher order theories.
We find an exact pp–gravitational wave solution of the fourth order gravity field equations. Outside the (delta–like) source this not a vacuum solution of General Relativity. It represents the contribution of the massive, m = (−β)−1/2, spin–two field associated to the Ricci squared term in the gravitational Lagrangian. The fourth order terms tend to make milder the singularity of the curvature ...
متن کاملGravitational Shock Wave Solution
We nd an exact pp{gravitational wave solution of the fourth order gravity eld equations. The sourceless version of it is not a vacuum solution of General Relativity. It represents the contribution of the massive, m = (?) ?1=2 , spin{ two eld associated to the Ricci squared term in the gravitational Lagrangian. We generalize this analysis to D{dimensions, extended sources, and higher than fourth...
متن کاملExact Implementation of Multiple Initial Conditions in the DQ Solution of Higher-Order ODEs
The differential quadrature method (DQM) is one of the most elegant and useful approximate methods for solving initial and/or boundary value problems. It is easy to use and also straightforward to implement. However, the conventional DQM is well-known to have some difficulty in implementing multiple initial and/or boundary conditions at a given discrete point. To overcome this difficulty, this ...
متن کاملExact Friedmann Solutions in Higher-Order Gravity Theories
We find the general behaviour of homogeneous and isotropic cosmological models in some fourth-order theories of gravity. Explicit, exact, general solutions are given for both empty universes and those filled with a perfect fluid. For the vacuum case, solutions are found with closed, open and flat geometries, whilst the perfect fluid solutions are all spatially flat. Both early and late-time lim...
