演讲人简介：现为英国剑桥大学教授。2018年8月获得了数学界最高奖菲尔兹奖。获奖工作包括对BAB猜想的证明（Fano簇的有界性）以及在极小模型纲领（Minimal Model Program）中的贡献。主要研究领域是代数几何(高维双有理几何，极小模型理论）

Biography：Caucher Birkar is a professor at the University of Cambridge in the United Kingdom. His research area is algebraic geometry. In the International Congress of Mathematicians in 2018, Prof. Caucher Birkar was awarded the Fields medal, the highest honor for mathematicians, for his works on boundedness of Fano varieties and the minimal model program.

演讲摘要：代数几何是核心数学的一个重要分支，它和数学的其它分支以及物理都有重要的联系。该报告将深入浅出地介绍代数几何中的一些基本概念。代数几何将代数和几何融合在一起，它起始于求解多项式方程组，这类问题引导人们去考虑这些方程定义的空间的形状，空间的几何反过来为研究抽象方程的提供了形象的直觉。

Abstract：This talk is a gentle introduction to some basic notions of algebraic geometry, a central field of mathematics with connections to many other parts of mathematics and also physics, etc. As the name suggests, algebraic geometry is a mixture of algebra and geometry. It all starts with solving polynomial equations but soon leads to considering the shapes of these equations which provides a way for our intuition to guide us through the world of abstract equations.
