SUMMARY:Han-Bom Moon\, Ulrich bundles on intersections of quadrics
DESCRIPTION:    Speaker\n\n\nHan-Bom Moon\nFordham University\n\n\n\n\n\n\nAn Ulrich bundle is a vector bundle with very strong cohomology vanishing conditions. Eisenbud and Schreyer conjectured that every smooth projective variety possesses an Ulrich bundle. Despite many results on low dimensional varieties and special varieties\, the general existence is unknown. In this talk\, I will describe recent work in progress with Kyoung-Seog Lee and Jiwan Jeong on the construction of Ulrich bundles on an intersection of quadrics.

SUMMARY:Sung Gi Park\, Hodge symmetries of singular varieties
DESCRIPTION:    Speaker\n\n\nSung Gi Park\nPrinceton U. / IAS\n\n\n\n\n\n\nThe Hodge diamond of a smooth projective complex variety exhibits fundamental symmetries\, arising from Poincaré duality and the purity of Hodge structures. In the case of a singular projective variety\, the complexity of the singularities is closely related to the symmetries of the analogous Hodge-Du Bois diamond. For example\, the failure of the first nontrivial Poincaré duality is reflected in the defect of factoriality. Based on joint work with Mihnea Popa\, I will discuss how local and global conditions on singularities influence the topology of algebraic varieties.

SUMMARY:Yoosik Kim\, Disk Counting via GIT Quotients
DESCRIPTION:    Speaker\n\n\nYoosik Kim\nPusan National University\n\n\n\n\n\n\nAccording to the Kempf–Ness theorem\, the GIT quotient is equivalent to the symplectic reduction. Using this correspondence\, we explain how to relate the counting of holomorphic disks between a symplectic manifold equipped with a Hamiltonian group action and its symplectic reduction. As an application\, we derive the disk potential function for weight varieties obtained as quotients by the maximal torus of partial flag varieties. We also demonstrate how the disk counting depends on the choice of stability conditions.

SUMMARY:Alex Abreu\, On the Torelli Theorem for graphs and stable curves
DESCRIPTION:    Speaker\n\n\nAlex Abreu\nUniversidade Federal Fluminense\n\n\n\n\n\n\nThe classical Torelli theorem states that a smooth curve can be recovered from its polarized Jacobian. In this talk\, we will discuss the extensions of this theorem to stable curves and their dual graphs\, as well as its dependence on the concept of compactified Jacobians. First\, we will recall Caporaso and Viviani’s theorem\, which characterizes when two stable curves have the same Caporaso’s compactified Jacobian. Then we will discuss Torelli’s theorem via fine compactified Jacobians. This is based on an ongoing joint work with Marco Pacini and Nicola Pagani.
