Singularities of Dual Varieties in Characteristic 3
نویسنده
چکیده
We investigate singularities of a general plane section of the dual variety of a smooth projective variety, or more generally, the discriminant variety associated with a linear system of divisors on a smooth projective variety. We show that, in characteristic 3, singular points of E6-type take the place of ordinary cusps in characteristic 0.

This paper is a slightly revised version of an introduction into singularity theory corresponding to a series of lectures given at the ``Advanced School and Conference on homological and geometrical methods in representation theory'' at the International Centre for Theoretical Physics (ICTP), Miramare - Trieste, Italy, 11-29 January 2010. We show how to associate to a triple of posit...

For nonsingular varieties, the one-dimensional case is an easy fact in curve theory. The two-dimensional case follows from the work of Reider [16]. In higherdimensional cases, (I) is known for n = 3 [3] and n = 4 [8], and by [1] we know that KX + 1 2 (n2 +n+ 2)D is generated by global sections for all n. Less is known about (II) with one exception: if D is already very ample, then (I) and (II) ...

The aim of this paper is to study the behavior of intersection homology genera and their associated characteristic classes under morphisms of projective algebraic varieties. We obtain formulae that relate (parametrized families of) global invariants of a projective variety X to such invariants of singularities of proper algebraic maps defined on X . Such formulae severely constrain, both topolo...
