Multiplicity and stability of closed geodesics on bumpy Finsler 3-spheres
Huagui Duan, Yiming Long
We prove that for every $\Q$-homological Finsler 3-sphere with a bumpy and irreversible metric , either there exist two non-hyperbolic prime closed geodesics, or there e…

Maximum solutions of normalized Ricci flows on 4-manifolds
Fuquan Fang, Yuguang Zhang, Zhenlei Zhang
We consider maximum solution , , to the normalized Ricci flow. Among other things, we prove that, if is a smooth compact symplectic 4-manifold su…
