Mixed Hodge Structures and Iterated Integrals I, by Zdzislaw Wojtkowiak

We generalize the Zagier conjecture concerning polylogarithms to all iterated integrals in one forms with logarithmic singularities on a projective line minus a finite number of points. We give a motivic proof following the ideas of Deligne-Beilinson.
