Towards algebraic iterated integrals on elliptic curves via the universal vectorial extension

Abstract

For an elliptic curve $E$ defined over a field $k\subset \mathbb{C}$, we study iterated path integrals of logarithmic differential forms on $E^{†}$, the universal vectorial extension of $E$. These are generalizations of the classical periods and quasi-periods of $E$, and are closely related to multiple elliptic polylogarithms and elliptic multiple zeta values. Moreover, if $k$ is a finite extension of $\mathbb{Q}$, then these iterated integrals along paths between $k$-rational points are periods in the sense of Kontsevich--Zagier.
