Toric Construction and Chow Ring of Moduli Space of Quasi Maps from $\mathbb{P}^1$ with Two Marked Points to $\mathbb{P}^1 \times \mathbb{P}^1$

Abstract

In this paper, we present explicit toric construction of moduli space of quasi maps from $\mathbb{P}^1$ with two marked points to $\mathbb{P}^1 \times \mathbb{P}^1$, which was first proposed by Jinzenji and prove that it is a compact orbifold. We also determine its Chow ring and compute its Poincar\'e polynomial for some lower degree cases.
