某些Irreducible Character度的平均值

The Average of Some Irreducible Character Degrees

Ramadan Elsharif, Mark L. Lewis

摘要:

我们感兴趣的是确定度不能被某个素数$p$整除的不可约特征标的度的平均值的界,该素数保证奇数阶的有限群$p$是$p$ -幂零的。我们找到了一个依赖于素数$p$的界。如果我们通过固定复数的一个子域$k$来进一步限制我们的平均值,然后计算其度不能被$p$整除且其值在$k$中的不可约特征标的度的平均值,那么我们将看到,我们得到了一个依赖于$p$和$k$的界。此外,我们找到的例子,使这些界限最好的可能。

英文摘要:

We are interested in determining the bound of the average of the degrees of the irreducible characters whose degrees are not divisible by some prime $p$ that guarantees a finite group $G$ of odd order is $p$-nilpotent. We find a bound that depends on the prime $p$. If we further restrict our average by fixing a subfield $k$ of the complex numbers and then compute the average of the degrees of the irreducible characters whose degrees are not divisible by $p$ and have values in $k$, then we will see that we obtain a bound that depends on both $p$ and $k$. Moreover, we find examples that make those bounds best possible.
