一阶弦论和Kodaira-Spencer方程。I

First Order String Theory and the Kodaira-Spencer Equations. I

O. Gamayun, A. S. Losev, A. Marshakov

摘要:

我们考虑一阶玻色弦论,由主算子扰动,对应于目标空间复杂结构的变形。我们计算了这个理论中的有效作用量,发现它与世界片共形不变性的一致性必然要求Kodaira-Spencer方程满足目标空间Beltrami微分。我们讨论的对称性的理论和它的重新表述的维尔本背景领域。

英文摘要:

We consider first-order bosonic string theory, perturbed by the primary operator, corresponding to deformation of the target-space complex structure. We compute the effective action in this theory and find that its consistency with the world-sheet conformal invariance requires necessarily the Kodaira-Spencer equations to be satisfied by target-space Beltrami differentials. We discuss the symmetries of the theory and its reformulation in terms of the vielbein background fields.
