We study stability properties of a finite set Sigma of n x n-matrices such
as paracontractivity, BV- and left convergent products (LCPs)-stability, an
d their relations to each other. The conjecture on equivalence of paracontr
activity and LCP-stability is proved. Moreover, we prove the equivalence of
the uniform BV-stability and the property of vanishing length of steps of
any trajectory of Sigma. (C) 2000 Elsevier Science Inc. All rights reserved
