我们在这里报告了以前工作的扩展，在该工作中我们已经证明了矩阵模型提供了计算p-自旋曲线的交数的工具。我们进一步讨论了半整数的一个推广，并对和作了更详细的讨论。在这些新的案例中，人们会发现来自Ramond部门的贡献，这是不存在于正整数的。对于半整数自旋，也考虑了Virasoro约束的存在性，特别是弦方程。通过对数矩阵模型研究了黎曼曲面边界的贡献。超对称随机矩阵是对混合正负穿孔的推广。
We report here an extension of a previous work in which we have shown that matrix models provide a tool to compute the intersection numbers ofp-spin curves. We discuss further an extension to half-integerp, and in more details forand. In those new cases one finds contributions from the Ramond sector, which were not present for positive integerp. The existence of Virasoro constraints, in particular a string equation, is considered also for half-integral spins. The contribution of the boundary of a Riemann surface, is investigated through a logarithmic matrix model. The supersymmetric random matrices provide extensions to mixed positive and negativeppunctures.
