Title:  Quasiautomorphisms of Grassmannian cluster algebras and webs

Abstract:   We will show that the cluster structures on Grassmannians and Fock-Goncharov spaces are related by a notion called a quasi-isomorphism of cluster algebras. Using this connection between these spaces, we obtain a large group of symmetries of their respective cluster structures. These symmetries provide evidence for conjectures of Fomin and Pylyavskyy explicitly describing the cluster variables in these cluster algebras in terms of Kuperberg's web basis.
