Bifurcations in Volume-Preserving Systems
(1539K, PostScript)

ABSTRACT.  We give a survey on local and semi-local bifurcations 
of divergence-free vector fields. These differ for low dimensions 
from `generic' bifurcations of structure-less `dissipative' vector 
fields, up to a dimension-threshold that grows with the co-dimension 
of the bifurcation.
