2 is the only even prime number. Moreover, prime numbers are fractal.
Collatz problem is divided by two parts which are even and odd numbers. When you have odd numbers, you put them in 3n+1. Then you always have even numbers, so you divide them by 2.
You repeat it over and over again, until you get 1.
At first, you have odd numbers (3-29). You put them in 3n+1. You see (10,16,22・・・,88). You divide them by 2 such as (5,8,11・・,44). Half of them are odd numbers which are yellow. The others are even numbers, so you keep dividing them by 2 such as (4,7,10,13,16,19,22). Green numbers are odd which is 50%. This is fractal. You see 1 in the end.

Hodge conjecture
Hodge conjecture is the algebraic topology of a non-singular complex algebraic variety. Therefore, elliptic curves should be correlated with it because of the rational point.
X is a compact complex manifold of complex dimension n. Moreover, its cohomology groups lie in degrees zero through 2n. Elliptic curves are the two dimensions, although you pile them in Riemann sphere. There must be a decomposition on its cohomology with complex coefficients.
(p,q) is harmonic forms. These are the cohomology classes represented by differential forms such as Z1,...,Zn.
Z is a complex submanifold of X.
α is integration.
You can also write this.
i:Z→X
α is integration.
You can also write this.
