我们在具有任意数量的句柄和边界的黎曼曲面上计算 Landau-Ginzburg 模型中的拓扑相关器。边界可以对应于 B 型的任意拓扑 D 膜。我们还允许在边界和整体上插入任意运算符。答案由一个显式公式给出，该公式可以被视为 C. Vafa 闭弦拓扑相关器公式的开弦推广。我们讨论如何将我们的结果扩展到朗道-金兹堡环折的情况。电子打印存档：http://lanl.arXiv.org/abs/hep-th/0305136
We compute topological correlators in Landau-Ginzburg models on a Riemann surface with arbitrary number of handles and boundaries. The boundaries may correspond to arbitrary topological D-branes of type B. We also allow arbitrary operator insertions on the boundary and in the bulk. The answer is given by an explicit formula which can be regarded as an open-string generalization of C. Vafa’s formula for closed-string topological correlators. We discuss how to extend our results to the case of Landau-Ginzburg orbifolds. e-print archive: http://lanl.arXiv.org/abs/hep-th/0305136
