设r为素数。本文给出了有限域上经典群的Sylow r-子群在其自然表示下的共轭性问题的构造和求解的有效算法。我们还提供了构造GL(n,Fq),Sp(2 m,Fq),GO(2 m +1,Fq),GO−(2 m,Fq),GO+(2 m,Fq)或[公式:见正文]的Sylow r-子群的正规化子的算法。这里描述的算法在岩浆计算机代数系统中实现。
Let r be a prime. We provide efficient algorithms to construct and solve the conjugacy problem for the Sylow r-subgroups of the classical groups over finite fields in their natural representations. We also provide algorithms to construct the normaliser of a Sylow r-subgroup of GL(n,Fq), Sp(2m,Fq), GO(2m+1,Fq), GO−(2m,Fq), GO+(2m,Fq) or [Formula: see text] . The algorithms described here are implemented in the Magma Computer Algebra System.
