“Almost periodic sequences attached to non-crystallographic root systems”

speaker: Philipp Lampe (Bielefeld University )

abstract: We study Fomin-Zelevinskys mutation rule in the context of non-crystallographic root systems. In particular, we construct almost periodic sequences of real numbers for the non- crystallographic root systems of rank 2 by adjusting the exchange relation for cluster algebras. Moreover, we describe a matrix mutation class in rank 3.
