Wormholes as a basis for the Hilbert space in Lorentzian gravity.
We carry out to completion the quantization of a Friedmann-Robertson-Walker model provided with a conformal scalar field, and of a Kantowski-Sachs spacetime minimally coupled to a massless scalar field. We prove that the Hilbert space determined by the reality conditions that correspond to Lorentzian gravity admits a basis of wormhole wave functions. This result implies that the vector space sp...
متن کاملHilbert space of wormholes.
Wormhole boundary conditions for the Wheeler-DeWitt equation can be derived from the path integral formulation. It is proposed that the wormhole wave function must be square integrable in the maximal analytic extension of minisuperspace. Quantum wormholes can be invested with a Hilbert-space structure, the inner product being naturally induced by the minisuperspace metric, in which the Wheeler-...
متن کاملGeneral Self-dual Lorentzian Wormholes in Teleparallel Theory of Gravity
We find the most general Self-dual Lorentzian Wormholes in a special class of teleparallel theory of gravitation. The spacetime of these wormholes is a static and it includes the Schwarzschild black hole, a family of naked singularity and a disjoint family of Lorentzian wormholes all of which have a vanishing scalar curvature R({}). The stability is studied using the equations of geodesic devia...

today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
Inflating Lorentzian wormholes.
It has been speculated that Lorentzian wormholes of the Morris-Thorne type might be allowed by the laws of physics at submicroscopic, e.g. Planck, scales and that a sufficiently advanced civilization might be able to enlarge them to classical size. The purpose of this paper is to explore the possibility that inflation might provide a natural mechanism for the enlargement of such wormholes to ma...
