面积大的小多边形

Small polygons with large area

Christian Bingane, Michael J. Mossinghoff

摘要:

如果多边形具有单位直径,则该多边形为\textit{small}。当$n$为偶数且$n\geq14$为偶数时,具有固定边数$n$的小多边形的最大面积未知。我们确定了一个改进的下界的最大面积的小$n$ -gon这种情况下。该改进影响了渐近展开的$1/n^3$项;先前的进展影响了不太重要的项。此界限的改进不能超过$O(1/n^3)$。对于$n=6$、$8$、$10$和$12$,我们构造的多边形具有最大面积。

英文摘要:

A polygon is \textit{small} if it has unit diameter. The maximal area of a small polygon with a fixed number of sides $n$ is not known when $n$ is even and $n\geq14$. We determine an improved lower bound for the maximal area of a small $n$-gon for this case. The improvement affects the $1/n^3$ term of an asymptotic expansion; prior advances affected less significant terms. This bound cannot be improved by more than $O(1/n^3)$. For $n=6$, $8$, $10$, and $12$, the polygon we construct has maximal area.
