Abstract:	For a complex connected simple linear algebraic group G of adjoint type, De Concini and Procesi constructed its wonderful compactification \bar{G}, which is a smooth Fano G\times G-variety enjoying many interesting properties. Assume G is not of type B3, it is shown that its wonderful compactification \bar{G} is rigid under Fano deformations. Namely, for any family of smooth Fano varieties over a connected base, if one fiber is isomorphic to \bar{G}, then so are all other fibers. This is a joint work with Qifeng Li (KIAS).
