  This is an introduction of a book called "strong regularity", to appear at
Ast\'erisque, containing:
  1) Yoccoz' proof of Jakobson theorem

  2) Berger's proof of the abundance of non-uniformly hyperbolic H\'enon like
endomorphisms arxiv.org/abs/0903.1473
  It gives an overview of the main examples and conjectures of non-uniformly
hyperbolic set for low dimensional dynamical systems. It compares the proofs of
parameter selections based on the concept of binding with those based on the
one of strong regularity.
