置换有限域上射影直线的四次有理函数

Rational functions of Degree Four that Permute the Projective Line over a Finite Field

摘要:

最近,Ferraguti和Micheli确定了置换$ \Bbb F_q$上的有限域上的投影线$\Bbb P^1(\Bbb F_q)$的三次有理函数。在本文中,使用不同的方法,我们确定所有的有理函数的程度四,置换的$\Bbb P^1(\Bbb F_q)$。

英文摘要:

Recently, rational functions of degree three that permute the projective line $\Bbb P^1(\Bbb F_q)$ over a finite field $ \Bbb F_q$ were determined by Ferraguti and Micheli. In the present paper, using a different method, we determine all rational functions of degree four that permute the $\Bbb P^1(\Bbb F_q)$.
