Exponential map
Appearance
In differential geometry, the exponential map is a generalization of the ordinary exponential function of mathematical analysis to all differentiable manifolds with an affine connection. Two important special cases of this are
- The exponential map for a manifold with a Riemannian metric, and
- The exponential map from a Lie algebra to a Lie group (for the latter see Exponential map (Lie theory).)
