Are polynomials modulo $1$ equidistributed?
It is an elementary exercise to show that for irrational $\alpha \in \mathbb{R}$, the sequence $\{ \alpha n \mod 1 \}_{n \in \mathbb{N}}$ is dense in $T := \mathbb{R}/\mathbb{Z}$. With more work, it ...

The prime numbers do not satisfies Benford's law
A set of numbers is said to satisfy Benford's law if the leading digit d (d ∈ {1, ..., 9}) occurs with probability,
$$ P(d)=\log_{10}(d+1)-\log_{10}d,$$
how do you prove that the prime numbers do ...

The first return time of an irrational rotation
For the probability space $([0,1),\mathcal{B},\lambda)$ and for an irrational $\theta \in (0,1)$ we have the map $Tx = x + \theta \bmod 1$. I'm trying to find an expression for $n(x):=\inf\{n \in ...

Irrational rotation and recurrence time
Let $\mathbb{T}=\mathbb{R}/\mathbb{Z}$ be the torus, and $\alpha\in(0,1)$ be an irrational number, then the transformation $T$ defined by $Tx=x+\alpha$ is the irrational rotation on $\mathbb{T}$.

Equidistribution results vs transcendence degree
Consider $\alpha =(\alpha_1, \dots, \alpha_n) \in \mathbb{R}^n$ linearly independent over $\mathbb{Q}$, then the map $q \mapsto q \alpha:= ( q \alpha_1, \dots, q \alpha_n)$ gives a dense embedding ...

Weyl Equidistribution Theorem and a Limit
At the moment, I'm studying Ergodic Theory and I find myself a little stuck.
The Weyl Equidistribution Theorem states that the following are equivalent:
1. For any $f \in L^{1}([0,1])$ and sequence ...
