A generic, hard transition to chaos

A hard-in-amplitude transition to chaos in a class of dissipative flows of broad applicability is presented. For positive
values of a parameter F, no matter how small, a fully developed chaotic attractor exists within some domain of additional
parameters, whereas no chaotic behavior exists for F < 0. As F is made positive, an unstable fixed point reaches an
invariant plane to enter a phase half-space of physical solutions; the ghosts of a line of fixed points and a rich heteroclinic
structure existing at F = 0 make the limits t --* +oc, F ~ +0 non-commuting, and allow an exact description of the chaotic
flow. The formal structure of flows that exhibit the transition is determined. A subclass of such flows (coupled oscillators
in near-resonance at any 2 : q frequency ratio, with F representing linear excitation of the first oscillator) is fully analysed
