• Under this suposition there is strong contraction in every direction, under iteration by , except in the direction corresponding to the characteristic multiplier near -1.
• Let x measure distance in this direction (along the "slow manifold"). Then all the dynamics may be approximated well (due to the draconian contraction) by the iteration confined to this 1D line:
