Tangent Cones, Tangent Spaces, Tangent Stars: Secant, Tangent, Tangent Star and Dual Varieties of aes to the involved varieties. We end the chapter by recalling the definition of dual variety, its first properties, the definitions of Gauss maps and the relations with reflexivity. Some exercises are introduced to complement the material presented.

The Hilbert Scheme of Lines Contained in a Variety and Passing Through a General Point,, we show in an elementary way that a lot of homogeneous varieties admit only trivial extensions, that is, those obtained by taking the cone .(., . ) with ., by constructing explicitly the cone via the study of the singularities of the corresponding Hilbert schemes of lines through a general point of ..

In particular, an astonishing simple proof of the famous Landman Parity Theorem for dual defective manifolds appears as an application of the tools developed in Chap. .
