In this paper we investigate the tau-functions for the stationary sector of Gromov–Witten theory of the complex projective line and its version, relative to one point. In particular, we construct the integral representation for the points of the Sato Grassmannians, Kac–Schwarz operators, and quantum spectral curves. This allows us to derive the matrix models.

$$\mathbf{P}^1$$ 的 Gromov-Witten 理论的平稳扇区的矩阵模型

在本文中，我们研究了复射影线的 Gromov-Witten 理论及其版本相对于一个点的静止扇区的 tau 函数。特别是，我们构建了 Sato Grassmannians、Kac-Schwarz 算子和量子光谱曲线的点的积分表示。这使我们能够推导出矩阵模型。
