报告摘要:The series of lectures is devoted to give a brief introduction to cluster algebras. Here we will focus on cluster algebras of geometric type.

In the first talk, we introduce basic definitions and examples of cluster algebras.

The second talk is devoted to introduce certain fundamental results in cluster algebras, such as the Laurent phenomenon and the finite type classification theorem. We will give a sketch of the proof of Laurent phenomenon.

The last talk aims to introduce three kinds of parametrization in cluster algebra: the $d$ and $g$-vectors parametrize the cluster variables and the $c$-vectors parametrize the coefficients.
