论文摘要
我们证明,有限的组$ g $与琐碎的可解决的激进主义者的订单以$ {\ rm acd}(g)$($ {\ rm acd}(g)$(不可约性字符的平均程度)限制。上面的拟合子组的索引是按照$ {\ rm acd}(g)$界定的,但是我们表明,在某些情况下,它是根据$ g $的不可约性字符的程度界定的,而$ g $的不可减少字符,而$ g $的不可约束,这些字符属于拟合子组的线性字符上。这使我们提出了Gluck猜想的精致版本。
We prove that the order of a finite group $G$ with trivial solvable radical is bounded above in terms of ${\rm acd}(G)$, the average degree of the irreducible characters. It is not true that the index of the Fitting subgroup is bounded above in terms of ${\rm acd}(G)$, but we show that in certain cases it is bounded in terms of the degrees of the irreducible characters of $G$ that lie over a linear character of the Fitting subgroup. This leads us to propose a refined version of Gluck's conjecture.
