Let $n\geq 3$ and consider the hypercubic family with parameter $t$, together with its excellent Frobenius lift $t\mapsto t^\sigma$. Fixed-point conjecture. The excellent Frobenius…

Let $F_N(t)=\sum_{n=0}^{N-1}f_nt^n$ be the truncation of $F(t)$ at $t^N$, and let $t\mapsto t^\sigma$ be the excellent Frobenius lift. The congruence … holds for every $m,s\geq 1$.…
