Linearizability of flows by embeddings

Abstract We consider the problem of determining the class of continuous-time dynamical systems that can be globally linearized in the sense of admitting an embedding into a linear system on a higher-dimensional Euclidean space. We solve this problem for dynamical systems on connected state spaces that are either compact or contain at least one nonempty compact attractor, obtaining necessary and sufficient conditions for the existence of linearizing $$C^k$$ C k embeddings for $$k\in \mathbb {N}_{\ge 0}\cup \{\infty \}$$ k ∈ N ≥ 0 ∪ { ∞ } . Corollaries include (i) several checkable necessary conditions for global linearizability and (ii) extensions of the Hartman-Grobman and Floquet normal form…
