Abstract: Cluster Algebras, introduced in 2001 by Fomin and Zelevinsky, are a kind of commutative ring equipped with special combinatorial structure. They appear in a range of contexts, from representation theory to mirror symmetry. After providing a gentle introduction to cluster algebras, I will report on one aspect of work-in-progress with Alfredo Nájera Chávez and Hipolito Treffinger. We show that for cluster algebras of finite type, the cluster algebra with universal coefficients is equal to a canonically identified subfamily of the semiuniversal family for the Stanley-Reisner ring of the cluster complex.
