摘要
Gong Z,Aldeen M和Elsner L在[A note on a generalized Cramer’s rule,Linear AlgebraApp.,2002,340:253-254]中给出结论:对任意的k,α∈Qk,n,β∈Qk,m有|Xα,β|=|A-1|AYαβ,其中A∈n×n可逆矩阵,AX=Y.本文给出交换环上Rao正则矩阵的广义Cramer法则.
Gong Z,Aldeen M and Elsner L in [A note on a generalized Cramer's rule,Linear Algebra App.,2002,340: 253-254] given the result: for any k,α∈Qk,n,β∈Qk,m,|Xα,β|=|A-1|AYβ^α,where An×n is a nonsingular matrix over field r(A)=n and AX=Y.In this paper,the generalized Cramer' ruler of Rao regular matrix over communicate rings was given.
