Abstract

Clarke's inverse function theorem for Lipschitz mappings states that a bi-Lipschitz mapping f is locally invertible about a point x(0) if the generalized Jacobian partial derivative f (x(0)) does not contain singular matrices. It is shown that under these assumptions the generalized Jacobian of the inverse mapping at f (x(0)) is the convex hull of the set of matrices that can be obtained as limits of sequences J(f)(x(k))(-1) with f differentiable in x(k) and x(k) converging to x(0). This identity holds as well if f is assumed to be locally bi-Lipschitz at x(0).
