STABILITY AND GENERICITY IN DYNAMICAL SYSTEMS [PDF]

, 1980
A general reference to this subject, with examples, written about the summer of 1967 is [7], (reported in a recent Bourbaki seminar by C. Godbillon). Here I will try to emphasize developments since. An important source of much of this more recent work should appear in the immediate future in [1].
