Cluster expansion formulas and perfect matchings
Gregg Musiker, Ralf Schiffler
We study cluster algebras with principal coefficient systems that are associated to unpunctured surfaces. We give a direct formula for the Laurent polynomial expansion of cluster v…

On cluster algebras arising from unpunctured surfaces II
Ralf Schiffler
We study cluster algebras with principal and arbitrary coefficient systems that are associated to unpunctured surfaces. We give a direct formula for the Laurent polynomial expansio…
