关于除环的乘法群的局部幂零极大子群

On locally nilpotent maximal subgroups of the multiplicative group of a division ring

Bui Xuan Hai

摘要:

设$D$是以$F$为中心的除环,$D^*$是$D$的乘法群.本文研究了$D^*$的局部幂零极大子群.给出了中心为无穷远的除环中局部幂零极大子群存在的条件。证明了若$M$是$F$上代数的局部幂零极大子群,则它要么是$D$的某个极大子域的乘法群,要么是局部有限中心群.如果,此外,我们假设$F$是有限的和$M$是幂零的,那么第二种情况不能发生,即$M$是$D$的某个极大子域的乘法群。

英文摘要:

Let $D$ be a division ring with the center $F$ and $D^*$ be the multiplicative group of $D$. In this paper we study locally nilpotent maximal subgroups of $D^*$. We give some conditions that influence the existence of locally nilpotent maximal subgroups in division ring with infinite center. Also, it is shown that if $M$ is a locally nilpotent maximal subgroup that is algebraic over $F$, then either it is the multiplicative group of some maximal subfield of $D$ or it is center by locally finite. If, in addition we assume that $F$ is finite and $M$ is nilpotent, then the second case cannot occur, i.e. $M$ is the multiplicative group of some maximal subfield of $D$.
