论文摘要
在此注释中，我们证明了A. Akopyan和V. Vysotsky的以下猜想：如果平面曲线的凸壳$γ$涵盖平面凸$ K $，则$ \ opperatorname {length} {length}（γ）（γ）\ geq \ geq \ geq \ geq \ peratatornAme {per}（k） - \ permotatat -k）此外，研究了这种不平等的所有平等案例。
In this note, we prove the following conjecture by A. Akopyan and V. Vysotsky: If the convex hull of a planar curve $γ$ covers a planar convex figure $K$, then $\operatorname{length}(γ) \geq \operatorname{per} (K) - \operatorname{diam} (K)$. In addition, all cases of equality in this inequality are studied.
