In the last few years string theory has led to important new insights in the microscopic theory of certain supersymmetric black holes as well as quantum field theory with extended supersymmetry. Furthermore, it has become clear that gravity and quantum field theory are often complementary descriptions of the same dynamics. The purpose of the research project described here is to investigate to what extent these results can be extended to more realistic, non-supersymmetric systems such as non-extremal black holes. On another front we propose to investigate cosmological implications of recently proposed string compactifications with large extra dimensions. In particular, alternative scenarios for inflation within brane-inspired cosmologies will be analysed.

在过去的几年中，弦理论在某些超对称黑洞的微观理论以及具有扩展超对称性的量子场论中产生了重要的新见解。此外，很明显，引力和量子场论通常是对同一动力学的互补描述。这里描述的研究项目的目的是调查这些结果在多大程度上可以扩展到更现实的非超对称系统，如非极端黑洞。在另一方面，我们建议调查宇宙学的影响，最近提出的弦紧化与大的额外维。特别是，膜启发宇宙学内的通货膨胀的替代方案将进行分析。
