Periods of Iterated Integrals of Holomorphic Forms on a Compact on a Compact Riemann Surface

Unipotent variations of mixed Hodge structure

“…In case r=l, J/J2~-H~(X,C), and ~x Albanese mapping. A similar, but not identical, construction of higher A1-baneses was given by Par~in [17] and studied by Hwang-Ma [14]. A mixed Hodge theoretic unipotent representation p is seen to induce a mapping Cp: Alb~(X)~ U(Vx); the composite, Cpo ~, defines a unipotent variation.…”
