Abstract

We study the stopping time of the Collatz map for a polynomial fF2[x]f \in \mathbb{F}_2[x], and bound it by O(deg(f)1.5)O({\rm deg} (f)^{1.5}), improving upon the quadratic bound proven by Hicks, Mullen, Yucas and Zavislak. We also prove the existence arithmetic sequences of unbounded length in the stopping times of certain sequences of polynomials, a phenomenon observed in the classical Collatz map.
