Journal ArticleDOI
Inflation, large branes, and the shape of space
TL;DR: In this paper, it was shown that the large brane instability of Seiberg and Witten eliminates the negative candidates in the context of string theory and leaves the flat, compact, three-dimensional manifolds, Conway's platycosms.
Journal ArticleDOI
Classical Euclidean Wormhole Solution and Wave Function for a Nonlinear Scalar Field
TL;DR: The classical Euclidean wormhole solution of the Born—Infeld scalar field is considered and the wormhole wave functions are regarded as solutions of quantum-mechanical Wheeler—Dewitt equation with certain boundary conditions.
Journal ArticleDOI
Answering a Basic Objection to Bang/Crunch Holography
TL;DR: In this article, the authors argue that the double boundary problem is a matter not of geometry but rather of how one chooses a conformal compactification: if one chooses to compactify in an unorthodox way, then the appearance of disconnectedness can be regarded as a *coordinate effect.
Journal ArticleDOI
Classical and quantum wormholes in a 5D compact Kaluza–Klein theory
TL;DR: In this paper, the authors studied the classical and quantum euclidean wormholes for an empty (4+1) dimensional Kaluza-Klein universe with a positive cosmological constant and a spatially flat Robertson-Walker type metric.

Answering a basic objection to bang/crunch holography
TL;DR: The double boundary problem is a matter not of geometry but rather of how one chooses a conformal compactification: if one chooses to compactify in an unorthodox way, then the appearance of disconnectedness can be regarded as a coordinate effect as discussed by the authors.
