List of Seminars On the Singular Loci of Higher Secants of Veronese Varieties Kangjin Han (DGIST) 14:00-14:50, online Manin’s Conjecture for a Log Del Pezzo Surface of Index 2 DongSeon Hwang (Ajou Univ.) 15:20-16:10, IBS B266 Ulrich Bundles on Cubic Fourfolds Yeongrak Kim (Pusan National Univ.) 16:30-17:20, IBS B266
Speaker Kangjin Han DGIST (This is a part of Algebraic Geometry Day at CCG in IBS.) For a projective variety X in PN, the k-secant variety σk(X) is defined to be the closure of the union of k-planes in PN spanned by k-points of X. In this talk, we consider singular loci of higher …
Speaker DongSeon Hwang Ajou Univ. (This is a part of Algebraic Geometry Day at CCG in IBS.) Manin’s conjecture predicts the asymptotic behavior on the number of rational points of bounded anticanonical height on Fano varieties. In this talk, I will explain how the geometry governs the arithmetic in the case of a …
Speaker Yeongrak Kim Pusan National Univ. (This is a part of Algebraic Geometry Day at CCG in IBS.) Ulrich bundles are geometric objects corresponding to maximally generated maximal Cohen-Macaulay modules, whose existence has several interesting applications in commutative algebra, homological algebra, and linear algebra. After a pioneering work of Beauville and Eisenbud-Schreyer, existence …
