有限域上Cremona群的Jordan性质

Jordan property for Cremona group over a finite field

Yuri Prokhorov, Constantin Shramov

摘要:

证明了有限域上秩为$2$的Cremona群是Jordan群,并给出了当域中元素个数不同于$2$,$4$和$8$时,其Jordan常数的上界.

英文摘要:

We show that the Cremona group of rank $2$ over a finite field is Jordan, and provide an upper bound for its Jordan constant which is sharp when the number of elements in the field is different from $2$, $4$, and $8$.
