The $p$-powers dividing certain exponential sums

Antonine Phigareau · 2026

We define the notion of couple density $(D, \mathbf b)$ where $D$ is a non-empty subset of $\mathbb Z^{m}$ and $ \mathbf b$ a fixed element in $\{0, \cdots, q-2\}^{m};$ We determine a minimum in terms…

Selection Rules and Channel Structure in a Base Octave Model of Collatz Dynamics

Katharina Lodders · 2026

The Collatz iteration is governed by two distinct update rules, depending on the parity of the current iterate: n(i+1)=3n(i)+1 for odd n(i), and n(i+1)=n(i)/2 for even n(i). We show that these rules c…
