R.İnanç Baykur（马萨诸塞州阿默斯特大学）：通过正因子分解的小辛和奇异4-流形。我们将讨论新的想法和技术，用于产生表面映射类的正Dehn扭曲因子分解（与Mustafa Korkmaz共同工作），通过Lefschetz纤维化和铅笔产生有趣的辛和光滑4-流形的新结构，例如小的辛Calabi-Yau曲面和奇异有理曲面。
R. İnanç Baykur (University of Massachusetts Amherst): Small symplectic and exotic 4-manifolds via positive factorizations. We will discuss new ideas and techniques for producing positive Dehn twist factorizations of surface mapping classes (joint work with Mustafa Korkmaz), which yield novel constructions of interesting symplectic and smooth 4-manifolds, such as small symplectic Calabi-Yau surfaces and exotic rational surfaces, via Lefschetz fibrations and pencils.
