For the nonlinear discrete dynamical system Xk + 1 = Tx(k) on bounded, clos
ed and convex set D subset of R-n, we present several sufficient and necess
ary conditions under which the unique equilibrium point is globally exponen
tially asymptotically stable. The infimum of exponential bounds of converge
nt trajectories is also derived. (C) 2001 Academic Press.
