XXIX: 16, 166-180, LNM 1613 (1995) APPLEBAUM, David A horizontal Lévy process on the bundle of orthonormal frames over a complete Riemannian manifold (Stochastic differential geometry, Markov processes) This is an attempt to define a manifold-valued Lévy process by solving a SDE driven by a Euclidean Lévy process; but the author shows that the so-obtained processes are not Markovian in general. Comment: The existence and uniqueness statements are a particular case of general theorems due to Cohen (Stochastics Stochastics Rep.56, 1996). The same question is addressed by Cohen in the next article 2917 Keywords: Semimartingales with jumps, Lévy processes, Infinitesimal generators Nature: Original Retrieve article from Numdam
