用Losev技巧驯服开/闭弦对偶
Taming open/closed string duality with a Losev trick
摘要：
通过对具有离壳引力背景的全纯Chern-Simons理论进行Batalin-Vilkovisky量子化，给出了开和闭B模型的目标空间弦场论表述.得到了开弦全纯反常方程系数的目标空间表达式。此外，开/闭弦对偶证明了从一个明智的开放弦领域的整合。特别地，通过限制连续开模独立的情况，再现了[7]的移位公式，并因此示出了对闭弦对偶的数据进行编码。
英文摘要：
A target space string field theory formulation for open and closed B-model is provided by giving a Batalin-Vilkovisky quantization of the holomorphic Chern-Simons theory with off-shell gravity background. The target space expression for the coefficients of the holomorphic anomaly equation for open strings are obtained. Furthermore, open/closed string duality is proved from a judicious integration over the open string fields. In particular, by restriction to the case of independence on continuous open moduli, the shift formulas of [7] are reproduced and shown therefore to encode the data of a closed string dual.
