The dynamics of the normal form of the Takens-Bogdanov bifurcation with D-4
symmetry is governed by a one-dimensional map near the gluing bifurcation
and near the O(2) integrable limit, rather than the three-dimensional map o
ne would expect. This great simplification allows a quantitative descriptio
n of the bifurcation sequence through which stability is transferred betwee
n invariant subspaces. (C) 2001 Elsevier Science B.V. All rights reserved.
