1. Speaker: Dongwen Liu, Zhejiang University

Time: 9:30-10:30

Title：Introduction to resolvent rings

Abstract：Following Bhargava, we introduce the notion of formal "Galois closure", called the S_k-closure, for rings of rank k. Then we explain the quadratic resolvent of a cubic ring, which gives a concrete ring-theoretic interpretation of the parametrization of cubic rings by Delone and Faddeev.

2. Speaker: Yongqiang Zhao, Westlake University

Time: 11:00-12:00

Title: Parametrization of quartic rings (I)

Abstract: In the first of this series of talks, we will give an introduction to the parametrization theory of quartic rings. We will state the main results and explain its geometric analogue. We will also indicate its connection to representation theory.

3. Speaker: Yigeng Zhao, Westlake University

Time: 14:30-16:00

Title： Galois closure for extension of rings (I)

Abstract: We will introduce a notion of Galois closure for extension of rings, which is a generalization of the usual notion of Galois closure for extension of fields.
