Polylogarithms, Multiple Zeta Values and Superstring Amplitudes
Seminar Room 1, Newton Institute
AbstractSuperstring Theory is one of the most promising candidates for a quantum theory of gravity. Its interactions involve all kinds of multiple 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 string tension gives rise to iterated integrals within the [0,1] interval. I will discuss polylogarithm manipulations required for their systematic reduction to multiple zeta values.
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
