Xia Liao (Kaiserslautern): Chern classes of logarithmic derivations for free divisors
Wednesday, 23.04.2014 16:30 im Raum N2
Abstract: The sheaf of logarithmic derivations is an important object to
study. In this presentation, I will focus on the question of comparing the
Chern class of the logarithmic derivations of a free divisor and the
Chern-Schwartz-MacPherson class of the complement of the divisor. When the
Jacobian ideal of the free divisor is of linear type, the two classes
mentioned above are the same. I will also explain how this result is related
to the Logarithmic Comparison Theorem (LCT).
