A $p$-adic Approach To Piecewise Polynomial Dynamical Systems (2103.12251v1)

Abstract: Using $p$-adic numbers, we partially categorize the cycles of a sizable class of polynomial dynamical systems. In turn, we prove a few results related to the non-trivial cycles of the $\textit{Collatz map}$ $\text{Col} : \mathbb{Z}+ \to \mathbb{Z}+$ defined by $$\text{Col}(n) = \begin{cases} 3n + 1, & n \text{ is odd;} \ n/2, & \text{otherwise.}\end{cases}$$ Proving the non-existence of non-trivial Collatz cycles would reduce the Collatz conjecture to whether the Collatz map can diverge to infinity.
