Localized Intersections of Non-Extremal p-branes and S-branes

TL;DR

This paper introduces new supergravity solutions describing intersecting non-extremal p-branes and S-branes, with potential applications in time-dependent phenomena and cosmology within String Theory.

Contribution

It extends semi-local intersection solutions to non-extremal p-branes, including black-branes and D-ar{D} systems, and explores their interpretation as brane and S-brane intersections.

Findings

Solutions admit interpretation as D-brane and S-brane intersections.

Examples involve black-branes and D-ar{D} systems.

Potential relevance to cosmology and AdS/CFT time-dependent phenomena.

Abstract

A class of solutions to Supergravity in 10 or 11 dimensions is presented which extends the non-standard or semi-local intersections of Dp-branes to the case of non-extremal p-branes. The type of non-extremal solutions involved in the intersection is free and we provide two examples involving black-branes and/or D-\bar{D} systems. After a rotation among the time coordinate and a relatively transverse radial direction the solutions admit the interpretation of an intersection among D-branes and S-branes. We speculate on the relevance of these configurations both to study time dependent phenomena in the AdS/CFT correspondence as well as to construct cosmological brane-world scenarios within String Theory admitting accelerating expansion of the Universe.
