摘要
研究了平面卵形区域的Ros等周亏格问题,利用R^2中卵形区域的Ros定理及其加强形式,著名的等周不等式,给出R^2中卵形区域与Ros等周亏格相关的几个逆Bonnesen型不等式.
In this paper,we studied Ros isoperimetric deficit limits of the oval domain,based on the Ros theorem and it＇s Strengthen form of the oval domain in R2,we obtain Some Reverse Bonnesen style Inequaliyies related to Ros Isoperimetric Deficit of the oval domain in R2.
