本文研究固定边界自切比雪夫半径的凸多边形周长最小化问题,完整解决了 n=4 的情形,证明最小周长四边形为魔法风筝形,从而验证了 Rolf Walter 的猜想。
摘要:
本文研究欧氏平面上凸多边形的一些极值问题,这些问题与多边形边界的自切比雪夫半径概念相关。我们考虑在所有具有固定边界自切比雪夫半径的 n 边形中最小化周长的一般问题。本文的主要结果是对 n=4 时上述问题的完整解答:我们证明了最小周长的四边形是所谓的魔法风筝形,这验证了 Rolf Walter 提出的相应猜想。
英文摘要:
The paper is devoted to some extremal problems for convex polygons on the Euclidean plane, related to the concept of self Chebyshev radius for the polygon boundary. We consider a general problem of minimization of the perimeter among all $n$-gons with a fixed self Chebyshev radius of the boundary. The main result of the paper is the complete solution of the mentioned problem for $n=4$: We proved that the quadrilateral of minimum perimeter is a so called magic kite, that verified the corresponding conjecture by Rolf Walter.
