Variable tension brane-worlds

TL;DR

This paper explores models of brane-worlds with a 3+1 dimensional curved brane whose tension varies over time, contributing to understanding dynamic brane-world cosmologies.

Contribution

It introduces a new class of codimension one brane-world models featuring time-dependent brane tension, expanding the theoretical framework of brane-world scenarios.

Findings

Demonstrates consistent solutions with variable brane tension

Analyzes effects of tension variation on brane curvature

Provides groundwork for dynamic brane-world cosmology models

Abstract

I present recent work on codimension one brane-world models containing a 3+1 dimensional curved brane with time-dependent brane tension.
