Gravitational and cosmological properties of a brane-universe
David Langlois (IAP, Paris)
TL;DR
This paper introduces models where our universe is a 4D brane in higher dimensions, exploring their gravitational and cosmological properties with one extra dimension.
Contribution
It provides an overview of recent models of brane-universes, focusing on gravitational and cosmological implications with a single extra dimension.
Findings
Analysis of gravitational behavior in brane-world models
Cosmological dynamics in higher-dimensional frameworks
Implications for universe's evolution and matter confinement
Abstract
The aim of this contribution is to provide a short introduction to recently investigated models in which our accessible universe is a four-dimensional submanifold, or brane, embedded in a higher dimensional spacetime and ordinary matter is trapped in the brane. I focus here on the gravitational and cosmological aspects of such models with a single extra-dimension.
