Title    name 2013 KAIST Winter School on Algebraic Geometry     Title Generic inner projections of projective varieties and an application to the positivity of double point divisors 2   Speaker Atsushi Noma   Date 2013-01-24   Host   Place KAIST   File     Abstract : Generic projection of a projective variety plays an important role in projective geometry of algebraic varieties. In this talk, we discuss a) the nonbirational centers of projections of a projective variety; and b) the exceptional divisor of a generic inner projection of a projective variety. As an application, we study the positivity of double point divisors of a smooth projective variety.
