On the common index jump theorem and further developments
Huagui Duan, Yiming Long, Wei Wang +1
In [LZ02] published in Annals of Mathematics, Long and Zhu established originally the common index jump theorem (CIJT) for symplectic paths in 2002, which has played an important r…
Three closed characteristics on non-degenerate star-shaped hypersurfaces in
Huagui Duan, Hui Liu, Yiming Long +2
In this paper, we prove that for every non-degenerate compact star-shaped hypersurface in which carries no prime closed characteristic of Maslov-type ind…
Non-hyperbolic closed characteristics on non-degenerate star-shaped hypersurfaces in
Huagui Duan, Hui Liu, Yiming Long +1
In this paper, we prove that for every index perfect non-degenerate compact star-shaped hypersurface , there exist at least non-hyperbolic closed characte…
The existence of two closed characteristics on every compact star-shaped hypersurface in
Hui Liu, Yiming Long
Recently, Cristofaro-Gardiner and Hutchings proved that there exist at least two closed characteristics on every compact star-shaped hypersuface in . Then Ginzburg, Hein…
