摘要
Given an orbit space M/Gamma and an equivalence relation defined in it by means of the action of a group G, we obtain a miniversal deformation of an orbit through a miniversal deformation in M with regard to a suitable group action of G x Gamma. We show some applications to the perturbations of m-tuples of subspaces and (C, A)-invariant subspaces. (C) 2003 Elsevier Inc. All rights reserved.
