摘要
本文主要是对Poincare-Birkhoff扭转定理进行探讨,对扭转映射的连续性条件做了改进,给出非保面积部分扭转映射至少有一个不动点,而非保面积扭转映射至少有2个不动点的结论。
In the paper,Poincare-Birkhoff twisting theorem is primarily studied.Amending the condition of continuousness,the partly twisting T-map has at least one fixed point and the twisting T-map has at least two fixed points,which are not necessarily an area-preserving homomorphism.
