TL;DR
This review covers gravity on branes, especially codimension 1 models, and highlights a new result showing that the cosmological evolution of a 3-brane in the Dvali-Gabadadze-Porrati model can follow the standard Friedmann equation.
Contribution
It provides an overview of brane gravity theories and introduces a new finding on the cosmological behavior of 3-branes in the Dvali-Gabadadze-Porrati model.
Findings
Cosmological evolution of 3-brane can follow standard Friedmann equation.
Analysis of Newtonian limit on thin branes.
Discussion of black holes in Dvali-Gabadadze-Porrati model.
Abstract
This is an introductory review of gravity on branes with an emphasis on codimension 1 models. However, for a new result it is also pointed out that the cosmological evolution of the 3-brane in the model of Dvali, Gabadadze and Porrati may follow the standard Friedmann equation. Contents: 1. Introduction 2. Conventions 3. The Lanczos-Israel matching conditions 4. The action principle with codimension 1 hypersurfaces: Need for the Gibbons-Hawking term 5. The Newtonian limit on thin branes 6. A remark on black holes in the model of Dvali, Gabadadze and Porrati 7. The cosmology of codimension 1 brane worlds
