Adiceam–Nesharim–Lunnon's paperfolding counterexample conjecture

At least 1 year old · documented by

Let Υ(t)\mathcal{\Upsilon}(t) be the Laurent series associated with the Paperfolding sequence, and let tt-LCLC denote the p(t)p(t)-adic Littlewood Conjecture with p(t)=tp(t)=t. Adiceam–Nesharim–Lunnon's conjecture. If p≡3(mod4)p\equiv 3\pmod 4 is prime, then Υ(t)\mathcal{\Upsilon}(t) is a counterexample to tt-LCLC over fields of characteristic pp.

The conjecture is supported by computer evidence, while the source states that the characteristic-33 case was proved and this paper supplies further evidence in characteristics 77 and 1111.
