本文有两个主要结果。首先,我们通过给出劣素数的李型例外群的所谓拟孤立块来完成nite拟单群的所有p-块的参数化。这依赖于从适当的Levi子群中显式分解Lusztig诱导。我们的第二个主要结果是证明了Brauer在Nite群的块上长期存在的高度为零的猜想的一个方向,使用
This paper has two main results. Firstly, we complete the parametrisation of all p-blocks of nite quasi-simple groups by nding the so-called quasi-isolated blocks of exceptional groups of Lie type for bad primes. This relies on the explicit decomposition of Lusztig induction from suitable Levi subgroups. Our second major result is the proof of one direction of Brauer’s long-standing height zero conjecture on blocks of nite groups, using the
