In this paper, we present explicit toric construction of moduli space of quasi maps from [Formula: see text] with two marked points to [Formula: see text], which was first proposed by Jinzenji and prove that it is a compact orbifold. We also determine its Chow ring and compute its Poincaré polynomial for some lower degree cases.

从 ℙ1 到 ℙ1 × ℙ1 的准映射模空间的复曲面构造和 Chow 环

在本文中,我们提出了准映射模空间的显式复曲面构造,从 [公式:见文本] 到 [公式:见文本] 的两个标记点,这是由 Jinzenji 首次提出的,并证明它是一个紧凑的 orbifold。我们还确定了它的 Chow 环,并针对一些低度情况计算了它的 Poincaré 多项式。
