Title: A gentle introduction to cluster algebras


This is a gentle introduction to cluster algebra for general audience. I will carefully define the cluster algebras from quivers. I will emphasize the role of $g$-vectors in the theory. I will state a weak version of Fock-Goncharov conjecture. It would be helpful if you can install B. Keller's applet on your laptop and bring it to the seminar. The talk is friendly to undergraduates.
