Time-dependent solutions of gravity.
Jones, Gregory Chapman.

Time-dependent solutions of gravity. - 232 p.

Adviser: Andrew Strominger.

Thesis (Ph.D.)--Harvard University, 2006.

First, we describe the card diagram which is used to describe all Weyl-type spacetimes, and can be generalized beyond known Weyl types to include a cosmological constant. Card diagrams are extensions of Weyl half-planes to include time-dependent regions, and display all regions and global structure of a spacetime. Card diagrams have enabled the author and his collaborators to easily understand global structure of spacetime where pictureless methods would result in verbosity, confusion, or error. Additionally, card diagrams teach us about the structure of gravitational equations, sources, and solutions of PDEs/BVPs.

520 # $a First, we describe the card diagram which is used to describe all Weyl-type spacetimes, and can be generalized beyond known Weyl types to include a cosmological constant. Card diagrams are extensions of Weyl half-planes to include time-dependent regions, and display all regions and global structure of a spacetime. Card diagrams have enabled the author and his collaborators to easily understand global structure of spacetime where pictureless methods would result in verbosity, confusion, or error. Additionally, card diagrams teach us about the structure of gravitational equations, sources, and solutions of PDEs/BVPs.
520 # $a Fourth, we discuss the variety of S-branes, bubbles, and anti-bubbles obtainable from charged and spinning black holes in de Sitter and anti-de Sitter space.
520 # $a Lastly, we use these twisted bubbles in AdS5 to describe semiclassical decays of AdS5 orbifolds, and extend the Gibbons-Hawking thermodynamic formalism to the twisted case. We use card diagrams for AdS to argue the global structure in the Kerr AdS case, and find that a certain non-Killing event horizon remains present in the bubble spacetime for any a, b ≠ 0, so with a cosmological constant, the nonspinning case is highly nongeneric.
520 # $a Several new solutions of Einstein gravity, Einstein-Maxwell, and supergravity are presented. The solutions are derived, often from known solutions via analytic continuation, or generating or transformation methods. Then their properties and global structure are understood. Finally, their role in quantum gravity and string theory is described.
520 # $a Then, we look at solutions gotten from the black dihole geometry. We review the dihole wave, and the complicated S-dihole U -universes and E -universes. Scaling limits are discussed, and affine coordinates are emphasized for analyzing the complexified non-Killing 2-manifolds.
520 # $a Third, we give the correct global description of the odd-dimensional S-Kerr universes: D = 5, 7,9,.... All but the first ( D = 5) yield a new instanton which can be used to describe the semiclassical decay of a simpler spacetime into the S-brane.
