Dr. Peter Dalakov (Bulgarian Academy of Sciences, Sofia)
will give a talk on 

Generalised G_2 Hitchin systems, cubics and special Kaehler geometry

on Tuesday, July 5th, at 4 pm in Room 136, SISSA Building A.

Abstract: The base of the Hitchin integralble system for the exceptional group G_2 has a non-trivial involution L. As shown by Hitchin and Donagi-Pantev, for a sufficiently generic point b on the base, the Hitchin fibres over b and L(b) are dual abelian varieties. The involution L also preserves some of the special Kaehler data on the base. I will discuss some work in progress (with U. Bruzzo) on extending these results to the case of the generalised (ramified) Hitchin system.
