SUMMARY:Qifeng Li\, Rigidity of Wonderful Group Compactifications under Fano Deformations
DESCRIPTION:     Speaker\n\n\nQifeng Li\nIBS\, Center for Complex Geometry\n\n\n\n\n\nFor a complex connected semisimple linear algebraic group G of adjoint type and of rank n\, De Concini and Procesi constructed its wonderful compactification X\, which is a smooth Fano variety of Picard number n enjoying many interesting properties. In this talk\, we will show that the wonderful compactification X is rigid under Fano deformations. Namely\, for any family of smooth Fano varieties over a connected base\, if one fiber is isomorphic to X\, then so are all other fibers. This answers a question raised by Bien and Brion in their work on the local rigidity of wonderful varieties.
