Let $m$ be a positive integer and $q$ be a prime power. For large finite base fields $\mathbb F_q$, we show that any curve can be used to produce a complete $m$-arc as long as some generic explicit geometric conditions on the curve are verified. To show the effectiveness of our theory, we derive complete $m$-arcs from hyperelliptic curves and from Artin-Schreier curves.

在作者以前的工作中,提出了一个逐步算法FOP,它使用任意固定顺序的点在投影平面$\mathrm{PG}(2,q)$。在每一步中,该算法将不位于弧的二等分线上的固定顺序的第一点添加到当前弧。该算法是基于直观的假设,$\mathrm{PG}(2,q)$包含足够数量的相对较小的完整的弧。此外,在以前的文件中,它表明,在$\mathrm{PG}(2,q)$的点的顺序的类型是不相关的。$\mathrm{PG}(2,q)$中的完备lexiarc是通过算法FOP使用点的字典序获得的完备弧。在这项工作中,我们收集并分析了以下区域中的完整lexiarcs的大小:\begin{align*}& \textbf{all } q\le321007,~ q \mbox{ prime power}; & 15 \mbox{ sporadic $q$'s in the interval }[323761\ldots430007], \mbox{ see (1.10)}. \end{align*}在工作[9]中,收集了所有$q\leq160001$,$q$素数幂的$\mathrm{PG}(2,q)$中完整弧的最小已知大小。完整的弧的大小,收集在这项工作中,在[9],提供了以下上界的最小尺寸$t_{2}(2,q)$的一个完整的弧在投影平面$\mathrm{PG}(2,q)$:\begin{align*} t_{2}…

在投影平面$\mathrm{PG}(2,q)$中,我们收集区域\begin{align*} &\mbox{all } q\le160001,~~ q \mbox{ prime power};\\ &Q_{4}=\{34 \mbox{ sporadic }q'\mbox{s in the interval }[160801\ldots430007], \mbox{ see Table 3}\}. \end{align*}的完整弧的最小已知尺寸。对于$q\le160001$,弧尺寸的收集在考虑所有素数幂的弧的意义上是完整的。这证明了$\mathrm{PG}(2,q)$,特别是\begin{align*} t_{2}(2,q)&<0.998\sqrt{3q\ln q}<1.729\sqrt{q\ln q}&\mbox{ for }&&7&\le q\le160001;~~(1) \\ t_{2}(2,q)&<\sqrt{q}\ln^{0.7295}q&\mbox{ for }&&109&\le q\le160001;~~(2)\\ t_{2}(2,q)&<\sqrt{q}\ln^{c_{up}(q)}q,~~c_{up}(q)=\frac{0.27}{\ln q}+0.7,&\mbox{ for }&&19&\le q\le160001;~~(3)\\ t_{2}(2,q)&<0.6\s…
