关于SL $(2,q)$的共轭类

On conjugacy classes of SL$(2,q)$

Edith Adan-Bante, John M. Harris

摘要:

设SL(2,q)是大小为q的有限域F上行列式为1的2 × 2矩阵群.证明了:若q为偶数,则SL(2,q)的任意两个非中心共轭类的积是SL(2,q)的至少q-1个不同共轭类的并.另一方面,如果q>3是奇数,则SL(2,q)的任何两个非中心共轭类的乘积是SL(2,q)的至少(q+3)/2个不同共轭类的并。

英文摘要:

Let SL(2,q) be the group of 2X2 matrices with determinant one over a finite field F of size q. We prove that if q is even, then the product of any two noncentral conjugacy classes of SL(2,q) is the union of at least q-1 distinct conjugacy classes of SL(2,q). On the other hand, if q>3 is odd, then the product of any two noncentral conjugacy classes of SL(2,q) is the union of at least (q+3)/2 distinct conjugacy classes of SL(2,q).
