摘要
In this paper we define a new condition number adapted to directionally uniform perturbations in a general framework of maps between Riemannian manifolds. The definitions and theorems can be applied to a large class of problems. We show the relation with the classical condition number and study some interesting examples. (C) 2010 Elsevier Inc.
