Quivers, geometric invariant theory, and moduli of linear dynamical systems

Abstract

We use geometric invariant theory and the language of quivers to study compactifications of moduli spaces of linear dynamical systems. A general approach to this problem is presented and applied to two well known cases: We show how both Lomadze’s and Helmke’s compactification arises naturally as a geometric invariant theory quotient. Both moduli spaces are proven to be smooth projective manifolds. Furthermore, a description of Lomadze’s compactification as a Quot scheme is given, whereas Helmke’s compactification is shown to be an alg Show more
