  • Interesting fact: Experiments conducted in Germany and at the University of Southampton in England show that even mild and incidental noises cause the pupils of the eyes to dilate. It is believed that this is why surgeons, watchmakers, and others who perform delicate manual operations are so bothered by noise. The sounds cause their pupils to change focus and blur their vision.

The surface of stone with his forehead.

Having ever seen in his life.

Upon his smile.

In science:

Then, the fol lowing are equivalent: (1) The boundary dilatation coefficient αh (p) < +∞. (2) There exist a (necessarily unique) point q ∈ ∂D and a number λ > 0 such that h(ED (p, R)) ⊆ ED (q , λR), for al l R > 0.
Pluripotential theory, semigroups and boundary behavior of infinitesimal generators in strongly convex domains
The reason of the importance of boundary dilatation coefficients in iteration theory is that, while they give a global picture of the dynamics of a self-map of D , they can be easily computed as radial limits along any complex geodesic.
Pluripotential theory, semigroups and boundary behavior of infinitesimal generators in strongly convex domains
We say that a point p ∈ ∂D is a boundary regular fixed point, BRFP for short, if h has non-tangential limit p at p and the boundary dilatation coefficient αh (p) < +∞. A BRFP with boundary dilatation coefficient ≤ 1 is also called a stationary point.
Pluripotential theory, semigroups and boundary behavior of infinitesimal generators in strongly convex domains
In particular the map eρϕ ◦ h ◦ ϕ : D → D has BRFP at 1 with boundary dilatation coefficient αh (p).
Pluripotential theory, semigroups and boundary behavior of infinitesimal generators in strongly convex domains
Thus the classical Julia-Wolff-Carath´eodory theorem (see, e.g., ) implies that 1 is a BRFP for ζ 7→ eρϕ (h(ϕ(ζ ))) with boundary dilatation coefficient a < +∞.
