This proposal has many facets, most of which have to do with various theories of gauged supergravity. The PI proposes to study supersymmetric versions of the five dimensional Randall-Sundrum world brane scenario that has interesting features and may bring in some new ideas about the stability of brane configurations. The theories of gauged supergravities in five and six dimensions have not been explored in the past. It has become clear over the last few years that attempts of embedding world branes into supersymmetric theories are incomplete since not all versions of five and six dimensional gauged supergravities have been constructed. The PI proposes to study 5d supergravities with tensor multiplets and to consider the consequences for supersymmetric Randall-Sundrum brane world scenarios. Another aspect of the proposal is related to developments with gauged supergravities in various dimensions, including nine The PI proposes a new version of 9d gauged supergravity where it has been found that domain walls exist. This theory will be explored in the context of brane worlds as well as for cosmology. The PI proposes to study Noncommutative Supersymmetric Gauge and Gravity theories in background anti symmetric fields. The thrust will be to develop a consistent complex supergravity theory. The PI also proposes to study teleparallel superspace formulations of supergravity where there is the possibility of breakdown of local Lorentz symmetry.

这个提议有很多方面，其中大部分都与各种测量超引力理论有关。PI建议研究超对称版本的5维兰德尔-Sundrum世界膜场景，具有有趣的功能，并可能带来一些新的想法膜配置的稳定性。五维和六维的规范超引力理论在过去还没有被探索过。在过去的几年里，人们已经清楚地认识到，将世界膜嵌入超对称理论的尝试是不完整的，因为并不是所有的五维和六维规范超引力都被构造出来了。PI建议研究具有张量多重态的5d超引力，并考虑超对称Randall-Sundrum膜世界场景的后果。该提案的另一个方面与各种维度的规范超引力的发展有关，包括9维PI提出了一个新版本的9维规范超引力，其中发现存在畴壁。这个理论将在膜世界和宇宙学的背景下进行探索。 PI建议在背景反对称场中研究非对易超对称规范和引力理论。 重点将是发展一个一致的复杂超引力理论。PI还建议研究超引力的远程平行超空间公式，其中有可能破坏局部洛伦兹对称性。
