关于开弦与闭弦的对应

On the Correspondence of Open and Closed Strings

Marco Baumgartl

摘要:

本文研究开弦和闭弦之间的对应关系。这是在耦合开闭模空间的水平上,从弦场论的观点来完成的。Wess-Zumino-Witten模型上的边界弦场论的构造导致了一个关于闭弦背景在开弦场论中表现为非定域算子的猜想。快子凝聚导致弯曲膜的例子计算支持这个猜想。采取额外的步骤来研究超对称弦论理论的卡-丘流形的体积和边界模量的存在。对于拓扑B模型,我们计算了在开弦耦合下D5-膜的所有阶有效体诱导超势。

英文摘要:

This thesis investigates correspondences between open and closed strings. This is done on the level of coupled open-closed moduli spaces and from a string field theoretic point of view. The construction of boundary string field theory on Wess-Zumino-Witten models leads to a conjecture on closed string backgrounds appearing as non-local operators in open string field theory. Sample computations for tachyon condensation leading to curved branes support this conjecture. Additional steps are taken to study supersymmetric string theories on Calabi-Yau manifolds in the presence of bulk and boundary moduli. For the topological B-model effective bulk-induced superpotentials for D5-branes are computed to all orders in the open string couplings.
