如果G是一个特殊的射影线性群PSL(3,q),其中q = 4或7(mod 9),则G的一个Sylow 3-子群是9阶初等阿贝尔群。我们证明了任意两个这样的群的主3-块是Morita等价的。这个结果和奥山关于PSL(3,4)的定理证明了这些块的Broué猜想。1991年数学学科分类:20 C 05、20 C20。
If G is a projective special linear group PSL(3,q) with q ≡ 4 or 7 (mod 9), then a Sylow 3‐subgroup of G is elementary abelian of order 9. We show that the principal 3‐blocks of any two such groups are Morita equivalent. This result and Okuyama's theorem for PSL(3,4) prove the Broué conjecture for these blocks. 1991 Mathematics Subject Classification: 20C05, 20C20.
