Time-Symmetric Initial Data for Multi-Body Solutions in Three Dimensions
Alan R. Steif
Time-symmetric initial data for two-body solutions in three dimensional anti-deSitter gravity are found. The spatial geometry has constant negative curvature and is constructed as…
Supergeometry of Three Dimensional Black Holes
Alan R. Steif
We show how the supersymmetric properties of three dimensional black holes can be obtained algebraically. The black hole solutions are constructed as quotients of the supergroup $O…
Sphalerons and Conformally Compactified Minkowski Spacetime
G. W. Gibbons, Alan R. Steif
Solutions to the Yang-Mills field equations which describe exploding or imploding shells of gauge field and which may serve as approximations to the exploding sphaleron are discuss…
Phase Transition for Gravitationally Collapsing Dust Shells in 2+1 Dimensions
Yoav Peleg, Alan Steif
The collapse of thin dust shells in 2+1 dimensional gravity with and without a cosmological constant in analyzed. A critical value of the shell's mass as a function of its radius a…
Kinks and Time Machines
Andrew Chamblin, Gary Gibbons, Alan R. Steif
We show that it is not possible to smooth out the metric on the Deutsch-Politzer time machine to obtain an everywhere non-singular asymptotically flat Lorentzian metric.
Yang-Mills Cosmologies and Collapsing Gravitational Sphalerons
G. W. Gibbons, Alan R. Steif
Cosmological solutions with a homogeneous Yang-Mills field which oscillates and passes between topologically distinct vacua are discussed. These solutions are used to model the col…
