Remarks on the Isoperimetric Deficit of the Planar Isosceles Trapezoids of Constant Width
【摘要】 研究了平面常宽凸集K的等周亏格,验证了平面常宽等腰梯形K的Blaschke-Lebesgue定理,即当K为Reuleaux三角形时等周亏格最大.
【Abstract】 In this paper,we investigate the isoperimetric deficit of isosceles trapezoid of constant width.We confirm the known Blaschke-Lebesgue theorem for isosceles trapezoids of constant width.That is,the isoperimetric deficit of isosceles trapezoids of constant width attains the maximum for the Reuleaux triangle.
