摘要

Segre的切线引理可以追溯到20世纪50年代，当时他用它来证明他的“弧是二次曲线”定理。从那时起，它被用作证明各种物体的结果的工具，包括内部核、Kakeya集、具有少量奇割线的集以及弧的进一步结果。在这里，我们调查了其中的一些结果，并报告了Segre的切线引理的重新公式化是如何导致新的结果的。

On Segre's Lemma of Tangents

Segre's lemma of tangents dates back to the 1950's when he used it in the proof of his “arc is a conic” theorem. Since then it has been used as a tool to prove results about various objects including internal nuclei, Kakeya sets, sets with few odd secants and further results on arcs. Here, we survey some of these results and report on how re-formulations of Segre's lemma of tangents are leading to new results.

期刊介绍： Electronic Notes in Discrete Mathematics is a venue for the rapid electronic publication of the proceedings of conferences, of lecture notes, monographs and other similar material for which quick publication is appropriate. Organizers of conferences whose proceedings appear in Electronic Notes in Discrete Mathematics, and authors of other material appearing as a volume in the series are allowed to make hard copies of the relevant volume for limited distribution. For example, conference proceedings may be distributed to participants at the meeting, and lecture notes can be distributed to those taking a course based on the material in the volume.
