中文摘要: |
文中,对π-Fratini子群给出了更精细的结果,并将Gaschütz幂零性定理推广到π-局部定义群系.主要结果是:设G为有限群,H为G的次正规子群.若H/H∩Φ(G)Oπ′(G)∈F,则H∈Fπ,其中Fπ是π-可解π-局部定义群系. |
英文摘要: |
In this paper, our purpose is to make the results about π-Frattini subgroup more accurate, and to extend Gaschütz Theorem about nilpotency to π-locally defined formation. We come to Theorem Let G be a finite group, H a subnormal subgroup of G. If H/H∩Φ(G)O π′ (G)∈F, then H∈F π, where F π is π-solvable π-locally defined formation. |
