Steiner公式与等周不等式的变分证明

Steiner's formula and a variational proof of the isoperimetric inequality

Joseph Ansel Hoisington

摘要:

利用Steiner关于凸邻域面积的公式,给出了平面上等周不等式的一个新证明。这个证明直接建立了等周不等式,而不需要我们单独建立最优域的存在性。在这样做时,这个证明绕过了主要的困难,在所有的证明施泰纳概述的平面等周不等式。

英文摘要:

We give a new proof of the isoperimetric inequality in the plane, based on Steiner's formula for the area of a convex neighborhood. This proof establishes the isoperimetric inequality directly, without requiring that we separately establish the existence of an optimal domain. In doing so, this proof bypasses the main difficulty in all of the proofs Steiner outlined for the plane isoperimetric inequality.
