二维Kodaira-Spencer理论与三维Chern-Simons引力

Two Dimensional Kodaira-Spencer Theory and Three Dimensional Chern-Simons Gravity

Robbert Dijkgraaf, Cumrun Vafa

摘要:

受Kodaira-Spencer理论对Calabi-Yau三重的六维表述的启发,我们提出了一个二维的表述,并认为这是基于Riemann曲面几何的局部拓扑B模型目标空间的相关场论.我们证明了这个量子理论的沃德恒等式等价于最近由Eynard和Orantin提出的求解拓扑B模型的递归关系。我们的推导提供了一个概念上的解释,这种联系,并揭示了一个隐藏的仿射SL(2,R)对称性。此外,我们认为,我们的结果提供了最强有力的证据,拓扑M理论的存在,在一个更高的维度,在这种情况下,可以密切相关的SL(2,R)Chern-Simons制定的三维引力。

英文摘要:

Motivated by the six dimensional formulation of Kodaira-Spencer theory for Calabi-Yau threefolds, we formulate a two dimensional version and argue that this is the relevant field theory for the target space of local topological B-model with a geometry based on a Riemann surface. We show that the Ward identities of this quantum theory is equivalent to recursion relations recently proposed by Eynard and Orantin to solve the topological B model. Our derivation provides a conceptual explanation of this link and reveals a hidden affine SL(2,R) symmetry. Moreover we argue that our results provide the strongest evidence yet of the existence of topological M theory in one higher dimension, which in this case can be closely related to SL(2,R)Chern-Simons formulation of three dimensional gravity.
