TL;DR
This paper constructs novel time-dependent p-brane solutions in S-brane backgrounds, including AdS limits and singularities, and introduces a time-dependent dyonic membrane via deformation, expanding understanding of dynamic string theory backgrounds.
Contribution
It presents new time-dependent p-brane solutions with AdS limits and cosmological singularities, and applies a deformation to generate a dyonic membrane in 11 dimensions.
Findings
New M5- and D3-brane solutions with AdS limits
Presence of cosmological singularities in solutions
Time-dependent dyonic membrane configuration
Abstract
We construct time and radial dependent solutions that describe p-branes in chargeless S-brane backgrounds. In particular, there are some new M5- and D3-branes among our solutions which have AdS limits and contain a cosmological singularity as well. We also find a time-dependent version of the dyonic membrane configuration in 11-dimensions by applying a Lunin-Maldacena deformation to our new M5-brane solution.
