題目: Singularities at infinity of polynomial mappings

講師：Tat Thang Nguyen 

(Institute of Mathematics, Vietnam Academy of Sciences) 

概要:

Let F: C^n \to C^m be a polynomial mapping. It is  well-known that F

defines a locally trivial fibration outside some subset of C^m which is

called the "bifurcation set". In order to study the topology  of the map F

one problem should be solved is: to characterize the  bifurcation set of

F. In this talk, I will recall known results for this problem  and give

our solution for the problem in some particular cases.

このセミナーでは、多項式写像の分岐点と無限遠点における特異点に

ついてお話し頂きます。　大学院生ならびに教員の方々のご参加を

お待ちしています。
