[math-users] SISSA/IGAP algebraic geometry seminars

[Michele Graffeo]

Dear all,
      this is to announce the SISSA/IGAP algebraic geometry seminar,  
centered on intersection theory.

The aim of these seminars is to study intersection theory following  
the book of Fulton, Intersection Theory, and develop a working  
knowledge.
A comprehensive list of all speakers and topics covered can be found  
at the following webpage

ABSTRACT:   In this talk we will try to summarize the contents of  
Chapter 4 of the book. In particular, we will see how to generalize  
the notion of Segre class of a vector bundle to the case of an  
arbitrary cone (aka “singular vector bundle”). In the special case in  
which the cone is the normal cone to a closed subscheme, we will  
explain the behavior of the Segre class under the operations of  
pull-back and push-forward, and in particular the so called  
“birational invariance”.  Segre classes will be used in one of  
Fulton’s constructions of intersection products. Moreover, they appear  
naturally in many areas of Algebraic Geometry, and we will try to  
present some examples of these occurrences.


Best regards,
Andrea, Alessandro and Michele.
