Intrinsic Construction of Lyapunov Functions on Riemannian Manifold

Abstract: For systems evolving on a Riemannian manifold, we propose converse Lyapunov theorems for asymptotic and exponential stability. The novelty of the proposed approach is that is does not rely on local Euclidean coordinate, and is thus valid on a wider domain than the immediate vicinity of the considered equilibrium. We also show how the constructions can be useful for robustness analysis.
