四体共圆问题中心构型等腰梯形Four-Body Co-Circular Problem Central Configurations Isosceles Trapezoid



In 2012, Cors and Roberts [1] showed that the four-body co-circular central configuration is an isosceles trapezoid when two pairs of adjacent masses are equal. However, their proof is very complicated. In this paper, we give a simpler proof by using the method of oriented areas and mutual coordinates.
