摘要
本文是一系列四篇论文中的第四篇,旨在描述 M ̄ 3 \overline\{mathcal{M}}_{3} 的(近乎积分)Chow 环。 在本文中,我们最终计算了 M ̄ 3 的周环 Z [ 1 / 6 ]。 \mathbb{Z}[1/6] -系数。
This paper is the fourth in a series of four papers aiming to describe the (almost integral) Chow ring of M̄3\overline{\mathcal{M}}_{3}, the moduli stack of stable curves of genus 3.
In this paper, we finally compute the Chow ring of M̄3\overline{\mathcal{M}}_{3} with Z[1/6]\mathbb{Z}[1/6]-coefficients.
