SUMMARY:Yong Hu\, Noether-Severi Inequality and Equality for Irregular Threefolds of General Type
DESCRIPTION: Speaker\n\n\nYong Hu\nKIAS\n\n\n\n\n\n\nFor complex smooth irregular 3-folds of general type\, I will introduce the optimal Noether-Severi inequality. This answers an open question of Zhi Jiang in dimension three. Moreover\, I will also completely describe the canonical models of irregular 3-folds attaining the Noether-Severi equality. This is a joint work with Tong Zhang.

SUMMARY:Sukmoon Huh\, Logarithmic Sheaves on Projective Surfaces
DESCRIPTION: Speaker\n\n\nSukmoon Huh\nSungkyunkwan University\n\n\n\n\n\n\nA logarithmic sheaf is a sheaf of differential one-forms on a variety with logarithmic poles along a given divisor. One of the main problems on this object is to see whether Torelli property holds\, i.e. whether two different divisors define two non-isomorphic logarithmic sheaves. In this talk\, after reviewing some basic material\, we are going to introduce two new approaches to obtain Torelli property. This is a joint work in progress with S. Marchesi\, J. Pons-Llopis and J. Valles.

SUMMARY:Yonghwa Cho\, Cohomology of Divisors on Burniat Surfaces
DESCRIPTION: Speaker\n\n\nYonghwa Cho\nKIAS\n\n\n\n\n\n\nA (primary) Burniat surface is a complex surface of general type that can be obtained as a bidouble cover of del Pezzo surface with K2 = 6. The Picard group is an abelian group of rank 4 with torsion part isomorphic to (Z/2)6. Alexeev studied the divisors on Burniat surfaces\, and observed that the irreducible components of ramification divisors span the semigroup of effective divisors. Based on Alexeev’s result\, I will describe the method for computing cohomology of arbitrary divisors on Burniat surfaces. If time permits\, (non-)existence question about Ulrich bundles will be discussed as an application.
