The $$D_{\pi }$$-property on products of $$\pi $$-decomposable groups
Revista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas ( IF 2.9 ) Pub Date : 2020-11-01 , DOI: 10.1007/s13398-020-00950-z

The aim of this paper is to prove the following result: Let $\pi$ be a set of odd primes. If the group $G=AB$ is the product of two $\pi$-decomposable subgroups $A=A_\pi \times A_{\pi'}$ and $B=B_\pi \times B_{\pi'}$, then $G$ has a unique conjugacy class of Hall $\pi$-subgroups, and any $\pi$-subgroup is contained in a Hall $\pi$-subgroup (i.e. $G$ satisfies property $D_{\pi}$).

$$D_{\pi }$$- 对 $$\pi $$-可分解群的乘积的性质

本文的目的是证明以下结果:令 $\pi$ 是一组奇素数。如果群 $G=AB$ 是两个 $\pi$-可分解子群 $A=A_\pi \times A_{\pi'}$ 和 $B=B_\pi \times B_{\pi'} 的乘积$,那么$G$有一个唯一的Hall $\pi$-subgroups 共轭类,并且任何$\pi$-subgroup 都包含在一个Hall $\pi$-subgroup 中(即$G$ 满足属性$D_{\ pi}$)。
