چکیده
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 order theories.

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 کاملPeriodic Wave Shock solutions of Burgers equations
In this paper we investigate the exact peroidic wave shock solutions of the Burgers equations. Our purpose is to describe the asymptotic behavior of the solution in the cauchy problem for viscid equation with small parametr ε and to discuss in particular the case of periodic wave shock. We show that the solution of this problem approaches the shock type solution for the cauchy problem of the in...
متن کاملLocally Localized Gravity: The Inside Story
We derive the exact gravitational field of a relativistic particle localized on an AdS 3-brane, with curvature radius l, in AdS5 bulk with radius L. The solution is a gravitational shock wave. We use it to explore the dynamics of locally localized tensor gravitons over a wide range of scales. At distances below L the shock wave looks exactly like the 5D GR solution. Beyond L the solution approx...
متن کاملExact gravitational shock waves and Planckian scattering on branes
We obtain a solution describing a gravitational shock wave propagating along a Randall-Sundrum brane. The interest of such a solution is twofold: on the one hand, it is the first exact solution for a localized source on a Randall-Sundrum three-brane. On the other hand, one can use it to study forward scattering at Planckian energies, including the effects of the continuum of Kaluza-Klein modes....
متن کاملA Gravitational shock wave generated by a beam of null matter in quadratic qravity
In the present work we approximate an ultrarelativistic jet by a homogeneous beam of null matter with finite width. Then, we study the influence of this beam over the spacetime metric in the framework of higher-derivative gravity. We find an exact shock wave solution of the quadratic gravity field equations and compare it with the solution to Einstein’s gravity. We show that the effect of highe...
