On truncated logarithms of flows on a Riemannian manifold

Abstract

This paper gives quantitative global estimates between a time dependent flow on a Riemannian manifold (M)\left( M\right) and the flow of a vector field constructed by truncating the formal Magnus expansion for the logarithm of the flow. As a corollary, we also find quantitative estimates between the composition of the flows of two given time independent vector fields on MM and the flow of a truncated version of the Baker-Cambel-Hausdorff-Dynkin expansion associated to the two given vector fields.
