چکیده
The asymptotic behavior of Einstein-Rosen waves at null innnity in 4 dimensions is investigated in all directions by exploiting the relation between the 4-dimensional space-time and the 3-dimensional symmetry reduction thereof. Somewhat surprisingly, the behavior in a generic direction is better than that in directions orthogonal to the symmetry axis. The geometric origin of this diierence can be understood most clearly from the 3-dimensional perspective.

Gravitational waves with a space-translation Killing eld are considered. In this case, the 4-dimensional Einstein vacuum equations are equivalent to the 3-dimensional Einstein equations with certain matter sources. This interplay between 4-and 3-dimensional general relativity can be exploited eeectively to analyze issues pertaining to 4 dimensions in terms of the 3-dimensional structures. An ex...

We consider a Hamiltonian theory of spherically symmetric vacuum Einstein gravity under Kruskal-like boundary conditions in variables associated with the Einstein-Rosen wormhole throat. The connguration variable in the reduced classical theory is the radius of the throat, in a foliation that is frozen at the left hand side innnity but asymptotically Minkowski at the right hand side innnity, and...
متن کاملEinstein - Maxwell pp - waves
A large family of noncommutative Einstein-Maxwell null pp -waves to order one in the noncommutativity parameters is constructed. They are solutions to the Einstein and field equations for general relativity coupled to a Seiberg-Witten electromagnetic field. Noncommutativity enters the spacetime metric through a conformal factor and is responsible for dilating/contracting the separation between ...
