Schl\"afli function and iterated integrals


Speaker: Toshitake Kohno, University of Tokyo
Location: 693 Kerr
Start time: Mon, Oct 11 2004, 4:10PM

It is a well known fact due to Lobachevsky that the volume of a hyperbolic 3-simplex is expressed by dilogarithmic function. In this talk I will discribe in a more general situation a method to express hyperbolic volumes in terms of iterated integrals of logarithmic forms based on the idea of Aomoto. I will also discuss a relation to hypergeometric integrals associated with certain hyperplane arrangements.
