摘要
讨论群的元素性质与群的根性之间的关系.考虑群的元素性质P满足条件(1):如果x是G的P-元素,且N G,那么xN是G/N的P-元素;满足条件(4):设N⊿G,如果x∈N是G的P-元素,那么x也是N的P-元素,则群类P1={G|G的每个同态像没有非平凡的P-元素}是P1-根群类.如果P满足条件(1)和条件(2),x∈N是N的P-元素,且N⊿G,那么x也是G的P-元素,则群类P2={G|G的每个非平凡的同态像有一个非平凡的次正规P-子群}是P2-根群类.如果性质P满足条件(1),(2)和(4),那么P,P2均为根群类且P=P2.
In this paper, we make a discussion of the relationship between the properties of the elements of groups and the radical properties of groups. If the properties p of the elements of groups satisfies the conditions (1) if x is p-element of group G and N G, then xN is p-element of group G/N, and (4) let N G, if x 6 N is p-element of group G ,the x is p-element of 5/,then the class of groups P1 = { G | every image of G has not nontrivial p-elements} is p1-class of radical groups. If p satisfies the class of groups P2 = { G | every nontrivial image of G has a nontrivial p- subnormal subgroup } is p2-class of radical groups. If p satisfies the conditions (1), (2) and (4), then p, p1 are class of radical of groups, and P = P1.
