我们从IIB矩阵模型导出了时空坐标的长距离有效作用量。它为我们研究时空结构提供了一个有效的工具。我们证明了有限元N元理论对所有阶微扰理论的有限性。时空被证明是不可分的，其维度是动态确定的。IIB矩阵模型包含一种确保宇宙常数消失的机制，该机制不依赖于明显的超对称性。我们讨论了从IIB矩阵模型中获得真实维度和规范群的可能机制。
We derive a long distance effective action for space-time coordinates from a IIB matrix model. It provides us an effective tool to study the structures of space-time. We prove the finiteness of the theory for finite $N$ to all orders of the perturbation theory. Space-time is shown to be inseparable and its dimensionality is dynamically determined. The IIB matrix model contains a mechanism to ensure the vanishing cosmological constant which does not rely on the manifest supersymmetry. We discuss possible mechanisms to obtain realistic dimensionality and gauge groups from the IIB matrix model.
