Title: Real loci in particular ball quotients.


Abstract:

The moduli space M_{0,n} is the configuration space of n points on a projective line up to automorphisms. In 1986 Deligne and Mostow constructed a period map of M_{0,n} for n=5,6,8,12 to a ball quotient of dimension n-3. This generalizes the well known classical case n=4. Around 2000 various analoguous period maps have been found for configuration spaces of n points in the projective plane up to automorphisms for n=5,6,7,8 to ball quotients of dimension 2n-8. In the colloquium lecture I intend to explain the image of the real loci under the period map in the case of 6 points on a line and 6 points in the plane.

Colloquium coordinators are Prof.dr. A.C.D. van Enter (e-mail : A.C.D.van.Enter@rug.nl) and
Dr. A.V. Kiselev (e-mail: a.v.kiselev@rug.nl )
