Thời gian: 10h45-11h45, Thứ 6, ngày 19 tháng 10 năm 2018 Địa điểm: Hội trường tầng 2 nhà A6, 18B Hoàng Quốc Việt, Cầu Giấy, Hà Nội Tóm tắt: One of the fundamental problems in the classification of 4-manifolds topology is to find/construct a new family of 4-manifolds which were not known before. In this talk, I’d like to review various known techniques such as blowing-up, fiber-sum, Logarithmic transform, rational blow-down surgervy, Luttinger surgery and knot surgery which produce a new family of 4-manifolds in smooth, symplectic and complex categories. |
