Title & Abstract

• 허석문(Sukmoon Huh)(성균관대학교)

  Title : The net logarithmic tangent sheaves of complete intersections. 

  Abstract: The logarithmic sheaf is the sheaf of differential 1-forms with logarithmic poles along a reduced and effective divisor on a smooth projective variety. It is one of the main  

     ingredients to describe moduli space of stable sheaves, although it loses some information on the singularity of the divisor. In this talk, we suggest a way to encode singularity        

     information of the divisor to the logarithmic sheaf, using the construction of the logarithmic sheaf associated to complete intersection subvariety by D. Faenzi, M. Jardim and 

     J. Valles. I will explain some basic properties of this new logarithmic sheaf, together with applications. This is a joint work with Min-Gyo Jeong.

• 조용화(Yonghwa Cho)(경상국립대학교)

 Title : Double point divisors

 Abstract: Consider a (smooth) projective variety and a general linear projection onto a hypersurface. The projection morphism is finite and birational, so the non-isomorphic locus

     forms a proper closed subset. The double point divisor is the divisor supported on this non-isomorphic locus. In the first half of the talk, I will introduce more precise definition  

     and basic properties of double point divisors, based on the works of Mumford and Ilic. In the second half, I will discuss a joint work with Jinhyung Park regarding positivity 

     properties of double point divisors.
