In this paper, we construct explicit local examples of multidimensional Riemannian metrics whose geodesic flows have non-polynomial first integrals and are completely integrable. We rely on a construction described in a recent paper by A.V. Galajinsky which allows one to construct such examples via the Casimir invariants of finite-dimensional Lie algebras.
Keywords: Riemannian metric, geodesic flow, non-polynomial first integral, Lie algebra
Mots-clés : Casimir invariant.
