Izzet Coskun, The Higher Rank Brill-Noether Problem on Surfaces
B236-1 IBS, Korea, Republic ofSpeaker Izzet Coskun University of Illinois Chicago In this talk, I will explain how to use Bridgeland stability conditions to compute the cohomology of a general stable sheaf …
Luca Schaffler, An Explicit Wall Crossing for the Moduli Space of Hyperplane Arrangements
B236-1 IBS, Korea, Republic ofSpeaker Luca Schaffler Roma Tre University The moduli space of hyperplanes in projective space has a family of geometric and modular compactifications that parametrize stable hyperplane arrangements with …
Yen-An Chen, Toric Fano Foliations
B236-1 IBS, Korea, Republic ofSpeaker Yen-An Chen National Taiwan University In recent years, there are significant developments of the minimal model program for foliated varieties. It is intriguing to ask if Fano …
Luca Schaffler, Unimodal Singularities and Boundary Divisors in the KSBA Moduli of a Class of Horikawa Surfaces
B236-1 IBS, Korea, Republic ofSpeaker Luca Schaffler Roma Tre University Smooth minimal surfaces of general type with K2=1, pg=2, and q=0 constitute a fundamental example in the geography of algebraic surfaces, and …
Sungmin Yoo, Convergence of Sequences of the Bergman Type Volume Forms
B236-1 IBS, Korea, Republic ofSpeaker Sungmin Yoo Incheon National University Following the Yau-Tian-Donaldson conjecture, the construction of sequences of Bergman-type metrics converging to a canonical metric on a polarized manifold has been …
Yonghwa Cho, Double Point Divisors from Projections
B236-1 IBS, Korea, Republic ofSpeaker Yonghwa Cho Gyeongsang National University Consider a smooth projective variety of codimension e. A general projection from a linear subspace of dimension (e-2) is birational, hence the …
Sung Wook Jang, Potential Log Discrepancy and Minimal Model Program I
B236-1 IBS, Korea, Republic ofSpeaker Sung Wook Jang IBS CCG Minimal model program (abbreviated as MMP) is a central problem in birational geometry. The MMP is a sequence of divisorial contractions or …
Sung Wook Jang, Potential Log Discrepancy and Minimal Model Program II
B236-1 IBS, Korea, Republic ofSpeaker Sung Wook Jang IBS CCG We are interested in an anticanonical divisor and hope to establish the MMP for an anticanonical divisor. We believe that the beginning …
Sung Wook Jang, Potential Log Discrepancy and Minimal Model Program III
B236-1 IBS, Korea, Republic ofSpeaker Sung Wook Jang IBS CCG We can run an MMP for an lc pair. However, in general, we do not know whether the MMP terminates or not. …
