摘要
设G1,G2是群,映射f:G1→G2叫做G1到G2的广义同态映射,如果a,b∈G1,等式(ab)f=afbf和(ab)f=bfaf至少有一个成立.通过研究群的广义自同构群,该文得到了若干结果,推广了一些相关的经典定理,包括P.Hall关于自同构群的一个定理等.
Given groups G, and G2, a mapping f: G1→G2 is said to be a generalized homomorphism from G1 to G2 if for and a, b in G1, either (ab)^f = a^fb^f or (ab)s = b^fa^f. By studying the generalized automorphism groups , we obtain some results which generalize some related classical theorems, including a theorem of P. Hall on automorphism groups.
