    A Collatz-like variant governed by the dynamics of $\tau(n)$ and $\omega(n)$

    Following the nice discussion on my previous prime-based Collatz variant, I have designed a new system that incorporates the total number of divisors $\tau(n)$ and the number of distinct prime factors $\omega(n)$.
    Let $D(n)$ be defined for integers $n \ge 2$ as follows:...

    Reference that integer polynomials have few residues mod $N$ for some $N$

    Is there a version of the following result anywhere in the literature?
    Proposition 1. Let $p\in\mathbb{Z}[n]$ satisfy $\deg(p)\geq2$, and let $\varepsilon>0$. Then there is $N\in\mathbb{N}$ such that the set $\{p(n);n\in\mathbb{Z}\}$ intersects at most $\varepsilon N$ residue classes mod $N$....
