DESCRIPTION:Superstring Theory is one of the most promising candidates for
  a quantum theory of gravity. Its interactions involve all kinds of multip
 le zeta values\, and I will present how they emerge at the leading order (
 so-called tree level) of open string scattering amplitudes. The expansion 
 of the underlying generalized Gaussian hypergeometric functions in the str
 ing tension gives rise to iterated integrals within the [0\,1] interval. I
  will discuss polylogarithm manipulations required for their systematic re
 duction to multiple zeta values.\n
