Research Abstract

We studied analytic properties, special values and their relations with actions of Weyl groups, and functional relations for multiple zeta-functions associated with root systems. We proved several new formulas. In particular, we obtained functional relations and parity results for the zeta-function of the root system of type G_2, new relations for Euler-Zagier sums from the viewpoint of root systems of type C, and various properties of more general zeta-functions associated with Lie groups.
