SL_2(F_q)的第二对称幂表示的不变量

The invariants of the second symmetric power representation of SL_2(F_q)

Ashley Hobson, R. James Shank

摘要:

对于素数p>2和q=p^n,我们计算了第二对称幂表示的SL 2(F q)-不变量的有限生成集,证明了不变量是超曲面,分数域是系数域的纯超越扩张.作为中间结果,我们证明了Sylow p-子群的不变量也是超曲面。

英文摘要:

For a prime p>2 and q=p^n, we compute a finite generating set for the SL_2(F_q)-invariants of the second symmetric power representation, showing the invariants are a hypersurface and the field of fractions is a purely transcendental extension of the coefficient field. As an intermediate result, we show the invariants of the Sylow p-subgroups are also hypersurfaces.
