摘要
设F为一个元素个数大于3的域,T2(F)为F上的2×2上三角矩阵代数,P2(F)={A∈T2(F):A2=A},所有满足如下条件的映射:T2(F)→T2(F),A-λB∈P2(F)(A)-λ(B)∈P2(F),A,B∈T2(F),λ∈F构成集合Φ,本文研究Φ中元素的形式.
Suppose be an arbitrary field with at least 3 elements, T2(F) be2×2 upper triangular matrix algebras, P2(F) = {A ∈T2( F):A2 = A}. The set Φ based on the maps φ:T2( F)→T2(F) satisfies: A -λB∈ P2 (F)←→Φ(A) - λφ( B)∈ P2( F) , absolotely uneqvalto A,B∈ T2( F) ,λ∈ F.The maps of set φ are studied in this paper.
