»A rational blowdown surgery on 4-manifolds«

Abstract:
Since gauge theory was introduced in 1982, topologists and geometers working on 4-manifolds theory have developed various techniques and surgeries and they have obtained many fruitful and remarkable results on 4-manifolds in last 37 years. Among them, a rational blowdown surgery technique initially introduced by R. Fintushel and R. Stern and later generalized by J. Park turned out to be one of the simple but powerful techniques to construct a new family of 4-manifolds in various categories. In this talk, I'd like to brie y review what we have obtained in 4-manifolds topology by using a rational blowdown surgery.
