A class of quasisymmetric mappings with substantial points被引量:1
《Chinese Science Bulletin》2000年第4期313-316,共4页Zhong Li Shengjian Wu Yi Qi 
It is proved that Kq(h)=K0(h) for every h in some class of quasisymmetric mappings of the unit circle with substantial points, where Kq(h):=sup{M(h(Q))/M(Q); Qis a quadrilateral with the domain unit disk} and K0(h) is...

A conjecture of the length spectrum of Riemann surface
《Chinese Science Bulletin》1996年第10期793-797,共5页刘立新 
Let S0 be a compact Riemann surface with genus g,g>1. For any compact Riemannsurface S and any orientation preserved homeomorphism f:S0→S, we denote the pair (S,f) a marked Riemann surface....
