| 16:30 - 18:00 Algebraic Geometry Biweekly Webinar 2-Dimensional Stable Pairs on 4-Folds School MATHEMATICS I will discuss a 2-dimensional stable pair theory of nonsingular complex 4-folds that is parallel to Pandharipande-Thomas' 1-dimensional stable pair theory of 3-folds. The stable pairs of a 4-fold are related to its 2-dimensional subschemes via wall-crossings in the space of polynomial stability conditions. In Calabi-Yau case, Oh-Thomas theory is applied to define invariants counting these stable pairs under some restrains. This is a joint work with Yunfeng Jiang and Jason Lo. https://zoom.us/join Meeting ID: 9086116889 Passcode: 362880 ... |
