Query: Iterated integrals of modular forms and noncommutative modular symbols   The main goal of this paper is to study properties of the iterated integrals
of modular forms in the upper halfplane, eventually multiplied by $z^{s-1}$,
along geodesics connecting two cusps. This setting generalizes simultaneously
the theory of modular symbols and that of multiple zeta values
