TL;DR
This paper explores giant and dual giant gravitons in AdS spaces, demonstrating their BPS properties, supersymmetry preservation, and their role in realizing the stringy exclusion principle.
Contribution
It identifies BPS configurations of giant gravitons, introduces dual giant gravitons expanding into AdS, and discusses their implications for the stringy exclusion principle.
Findings
Giant gravitons are BPS and preserve the same supersymmetries as point gravitons.
Existence of dual giant gravitons expanding into AdS space.
Insights into the stringy exclusion principle within this framework.
Abstract
We investigate the `giant gravitons' of McGreevy, Susskind and Toumbas [hep-th/0003075]. We demonstrate that these are BPS configurations which preserve precisely the same supersymmetries as a `point-like' graviton. We also show that there exist `dual' giant gravitons consisting of spherical branes expanding into the AdS component of the spacetime. Finally, we discuss the realization of the stringy exclusion principle within this expanded framework.
