S.P. de Alwis
TL;DR
This paper examines the validity of the common factorisable metric ansatz in type IIB string theory with fluxes and branes, revealing contradictions with brane world cosmology and supporting previous critiques.
Contribution
It provides a detailed analysis of the limitations of the factorisable ansatz in 5D brane world models within IIB string theory, highlighting inconsistencies in cosmological applications.
Findings
Factorisable ansatz contradicts brane world cosmology results
Explicit identification of problems with the ansatz in IIB case
Supports previous critiques of the ansatz validity
Abstract
In computing potentials for moduli in for instance type IIB string theory in the presence of fluxes and branes a factorisable ansatz for the ten dimensional metric is usually made. We investigate the validity of this ansatz by examining the cosmology of a brane world in a five dimensional bulk and find that it contradicts the results obtained by using a factorizable ansatz. We explicitly identify the problem with the latter in the IIB case. These arguments support our previous work on this question.
