We discuss two arithmetical problems, at first glance unrelated:
1)
The properties of the multiple ζ-values
$$zeta ({n_{1, ldots,}}{n_m}): = sumlimits_{0 1$$
(1)
and their generalizations, multiple polylogarithms at N-th roots of unity.
2)
The action of the absolute Galois group on the pro-l completion
$$pi _1^{(l)}({X_N}): = pi _1^{(l)}({mathbb{P}^1}ackslash { 0{,_{mu N}},infty },upsilon )$$
of the fundamental group of X N := ℙ1{0, ∞ and all N-th roots of unity}.
