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.
