用$b^+=1$研究四维流形上的正规里奇流和光滑结构

On Normalized Ricci Flow and Smooth Structures on Four-Manifolds with $b^+=1$

Masashi Ishida, Rares Rasdeaconu, Ioana Suvaina

摘要:

利用$b^+=1$证明了四维流形上正规化里奇流非奇异解的存在性。利用这一障碍,我们研究了拓扑4-流形${\mathbb C}{P}^2 # l \overline{{\mathbb C}{P}^2}$上规范化里奇流非奇异解的存在性与奇异光滑结构之间的关系,其中$5 \leq l \leq 8$ .

英文摘要:

We find an obstruction to the existence of non-singular solutions to the normalized Ricci flow on four-manifolds with $b^+=1$. By using this obstruction, we study the relationship between the existence or non-existence of non-singular solutions of the normalized Ricci flow and exotic smooth structures on the topological 4-manifolds ${\mathbb C}{P}^2 # l \overline{{\mathbb C}{P}^2}$, where $5 \leq l \leq 8$.
