The Exponential of Skew-Symmetric Matrices: A Nearby Inverse and Efficient Computation of Derivatives

Zhifeng Deng, P. -A. Absil, Kyle A. Gallivan +1

The matrix exponential restricted to skew-symmetric matrices has numerous applications, notably in view of its interpretation as the Lie group exponential and Riemannian exponentia…
