摘要: 采用矩阵方法, 描述了二元域F2上一般线性群GLn(F2< /sub>)(n≥3)到任意域K上一般线性群GLn(K)的同态形式. 当Ch K≠2时, 给出 了GL3(F2)到GL3(K)的同态形式, 并证明当n≥4时, GL n(F2)到GLn(K)的同态是平 凡的; 当Ch K=2且n≥3时, 给出了GLn(F2)到GLn(K) 的同态形式.

Abstract: By using the matrix method, the present paper describes all the horomorphisms from the general linear group GLn(F2)(n≥3) over the field F2 with two elements into the general linear group GLn(K) over a fie ld K. If Ch K≠2, the characterization of the homomorphisms from GL 3(F2) into GL3(K) is given, and it is proved th at the homomorphisms from GLn(F2) into GLn(K) are trivial whenever n≥4; if Ch K≠2 and n≥3 , homomorphisms from GLn(F2) into GLn(K) are ch aracterized.
