Derivative of the Exponential Map Ethan Eade November 12, 2018 1 Introduction This document computes ¶ ¶e e=0 log exp(x +e)exp(x) 1 (1) where exp and log are the exponential mapping and its inverse in a Lie group, and x and e are elements of the associated Lie algebra. 2 Deﬁnitions Let Gbe a Lie group, with associated Lie algebra g. The matrix exponential is a much-studied matrix function having many applications. The Fréchet derivative of the matrix exponential describes the first-order sensitivity of $e^A$ to perturbations in A and its norm determines a condition number for $e^A$.
