Dyadic transformation

Binary cylinders make transitivity and density of periodic points transparent: concatenate prescribed finite blocks for transitivity and repeat a finite block for a periodic point.

Periodic points of the doubling map

F^{n}

are

x = \frac{j}{2 ^{n} - 1}, j = 0, \dots, 2^{n} - 2.

Thus

F^{n}

has

2^{n} - 1

For

n = 2^{k}

, every proper period dividing

n

divides

n /2

. Hence the number of points of exact period

2^{k}

(2^{2^{k}} - 1) - (2^{2^{k - 1}} - 1) = 2^{2^{k}} - 2^{2^{k - 1}} .

The term "dyadic transformation" can refer to different concepts depending on the context—it's not universally defined and may appear in various fields such as mathematics, physics, or even psychology. However, one prominent interpretation is in the context of **mathematics**, particularly in relation to **linear algebra** and **tensor analysis**. In a mathematical context, dyadic transformation typically refers to a transformation involving dyadic products, which are mathematical constructs used to represent linear maps between vector spaces.
