My former lecture series as part of the RTG days at Karlsruhe Institute of Technology and Heidelberg University. My lecture notes can be found here: Cluster algebras for Geometers.
The following link contains the computational reciepts for the proof of the A-coordinate structure of doubly extended cluster algebras
The cluster algebra explorer is a tool I developed to visualize the structure of cluster algebras. The tool allows the user to highlight codimension 1 subalgebras and orbits of A and X coordinates under the cluster modular group.
The ocaml library for cluster algebra computations can be found below. It is designed to generate and search cluster complexes and compute cluster modular groups. All the pictures above were generated using this and graphviz/gephi. There is specific support for grassmanian cluster combinatorics, but can work for arbitrary cluster algebras.
Cluster algebra codeMy personal notes from class. Hopefully everything is accurate but no guarentees.
