pp - waves
We obtain the pp-waves of D = 5 and D = 4 gauged supergravities supported by U (1) 3 and U (1) 4 gauged field strengths respectively. We show that generically these solutions preserve 1/4 of the supersymmetry, but supernumerary supersymmetry can arise for appropriately constrained harmonic functions associated with the pp-waves. In particular it implies that the solutions are independent of the...
متن کاملImpulsive spherical gravitational waves
Penrose’s identification with warp provides the general framework for constructing the continuous form of impulsive gravitational wave metrics. We present the 2-component spinor formalism for the derivation of the full family of impulsive spherical gravitational wave metrics which brings out the power in identification with warp and leads to the simplest derivation of exact solutions. These sol...
متن کاملExpanding impulsive gravitational waves
We explicitly demonstrate that the known solutions for expanding impulsive spherical gravitational waves that have been obtained by a “cut and paste” method may be considered to be impulsive limits of the Robinson–Trautman vacuum type N solutions. We extend these results to all the generically distinct subclasses of these solutions in Minkowski, de Sitter and anti-de Sitter backgrounds. For the...
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 ...
متن کاملDiagonalization of Pp-waves
A coordinate transformation is found which diagonalizes the axisym-metric pp-waves. Its effect upon concrete solutions, including impulsive and shock waves, is discussed.
