讲座简介:
We study projective cluster variables and projective lower bounds for cluster algebras arising from surfaces. In particular, we establish a complete characterization of when a compact cluster algebra from a surface with principal coefficients coincides with its projective lower bound. This is joint work with Jie Pan.
