    The stability of Killing–Cauchy horizons in colliding plane wave space-times

    It is confirmed rigorously that the Killing–Cauchy horizons, which sometimes occur in space-times representing the collision and subsequent interaction of plane gravitational waves in a Minkowski background, are

    Null Limits of the C-Metric

    The C-metric is usually understood as describing two black holes which accelerate in opposite directions under the action of some conical singularity. Here, we examine all the solutions of this type which repr...

    Null Limits of Generalised Bonnor-Swaminarayan Solutions

    The Bonnor-Swaminarayan solutions are boost-rotation symmetric space-times which describe the motion of pairs of accelerating particles which are possibly connected to strings (struts). In an explicit and unif...

    The Extensions of Gravitational Soliton Solutions with Real Poles

    We analyse vacuum gravitational“soliton” solutions with real poles in thecosmological context. It is well known that thesesolutions contain singularities on certain nullhypersurfaces. Using a Kasner seed solut...

    Perfect fluid space-times with a two-dimensional orthogonally transitive group of homothetic motions

    We use theghp formalism to obtain perfect fluid space-times with a two-dimensional and orthogonally transitive group of proper homothetic motionsH 2, with the additional condition that the four-velocity of the fl...

    A class of plane symmetric dust solutions

    A class of plane symmetric solutions containing dust is considered. It is argued that, however inhomogeneous the mass distribution, matter on each plane of symmetry has no net attraction to matter on other pla...

    Physical interpretation of vacuum solutions of Einstein's equations. Part II. Time-dependent solutions

    The study of interpretations of the vacuum solutions of Einstein's field equations is continued by considering some well known time-dependent solutions. Among these are metrics representing accelerating partic...

    Colliding plane gravitational waves with colinear polarization

    The colliding plane wave problem is considered using an unconventional coordinate system. This permits a complete solution to be explicitly stated for the general case of arbitrary approaching waves with const...

    A new class of exact solutions of the vacuum quadratic Poincaré gauge field theory

    A class of algebraically special exact solutions of the vacuum quadratic Poincaré gauge field theory is presented. These solutions are of type III and type N and have a nonexpanding, shear-free and twist-free ...

    The application of spin coefficient techniques in the vacuum quadratic Poincaré gauge field theory

    The vacuum field equations of the quadratic Poincaré gauge field theory are expressed in the spin coefficient formalism of Newman and Penrose. These are differential identities involving curvature and torsion ...
