Finding economical packing of circles in the euclidean plane is a widely investigated area of the theory of packing and covering . the simplest problem of this kind is to find the best arrangement of congruent discs in the plane
关于圆盘的填充问题的一个重要猜想是：在全等圆盘的填充中，密度最大填充可由正六边形阿基米德镶嵌中的内圆得到，这一猜想直到本世纪初才得以证明。
And then , in this part , following the idea of topping [ 51 , 52 ] , we will show an isoperimetric inequality ( 6 . 3 . 1 ) on surfaces of non - positive gaussian curvature by means of the curve shortening flow on surfaces , this inequality can be considered as a generalization of the banchoff - pohl inequality in the euclidean plane
然后，仿照topping [ 51 ]和[ 52 ]利用平均曲率流证明等周不等式的想法，我们利用曲面上的曲线缩短流在gauss曲率非正的曲面上证明了一个等周不等式( 6
