Pro-unipotent harmonic actions and dynamical properties of $p$-adic cyclotomic multiple zeta values

David Jarossay

Vol. 14 (2020), No. 7, 1711–1746
Abstract

p-adic cyclotomic multiple zeta values depend on the choice of a number of iterations of the crystalline Frobenius of the pro-unipotent fundamental groupoid of 1 {0,μN,}. In this paper we study how the iterated Frobenius depends on the number of iterations, in relation with the computation of p-adic cyclotomic multiple zeta values in terms of cyclotomic multiple harmonic sums. This provides new results on that computation and the definition of a new pro-unipotent harmonic action.

Keywords
$p$-adic cyclotomic multiple zeta values, cyclotomic multiple harmonic sums, pro-unipotent harmonic actions, projective line minus three points, pro-unipotent fundamental groupoid, crystalline Frobenius
