描述.This book explores the use of numerical relativity (NR) methods to solve cosmological problems, and describes one of the first uses of NR to study inflationary physics. NR consists in the solution of Einstein’s Equation of general relativity, which governs the evolution of matter and energy on cosmological scales, and in systems where there are strong gravitational effects, such as around black holes. To date, NR has mainly been used for simulating binary black hole and neutron star mergers like those detected recently by LIGO. Its use as a tool in fundamental problems of gravity and cosmology is novel, but rapidly gaining interest...In this thesis, the author investigates the initial condition problem in early universe cosmology – whether an inflationary expansion period could have “got going” from initially inhomogeneous conditions – and identifies criteria for predicting the robustness of particular models. State-of-the-art numerical relativity tools are developed in order to address this question, which are now publicly available..

Technical Background evolution, and the background to the specific problems studied. Discussion of the implementation aspects of the numerical evolution are left to the following chapter in which the code which was developed is described. As in Chap. ., we divide this chapter into three sections, GR, NR and Scalar Fiel

Inhomogeneous Inflation223, 1982, [.], Starobinsky, Phys Lett B 91:99–102, 1980, [.]) is thought to provide a solution to several problems in standard Big Bang theory by dynamically driving a “generic” initial state to a flat, homogeneous and isotropic Universe, while generating a nearly scale-invariant power spectrum of

Conclusions and Further Work code based on the BSSN/CCZ4 evolution scheme. It supports Berger-Collela type AMR evolution with Berger-Rigoutsos block structured grid generation and is fully parallelised via the Message Passing Interface. Time evolution is via standard 4th order Runge–Kutta time-stepping.
