Abstract:

In this talk we discuss certain extensions of mixed Hodge structures which
are coming from the mixed Hodge structure on certain graded quotients of
the group ring of the Fundamental group of a smooth projective pointed
curve. Such extensions are computed using iterated integrals. In a very
special case those iterated integral evaluated as a special values of
hypergeometric functions.
