We study the asymptotic proportion of smooth plane curves over a finite field which are tangent to every line defined over . This partially answers a question raised by Charles Favre. Our techniques include applications of Poonen's Bertini theorem and Schrijver's theorem on perfect matchings in regular bipartite graphs. Our main theorem implies that a random smooth plane curve over admits a transverse -line with very high probability.

关于无横向平面曲线的比例
我们研究有限域上的光滑平面曲线的渐近比例 与定义在上面的每条线相切 。这部分地回答了查尔斯·法弗(Charles Favre)提出的问题。我们的技术包括Poonen的Bertini定理和Schrijver定理在正则二部图中的完美匹配上的应用。我们的主要定理表明,在 承认横向 线的可能性很高。
