Recently, basing on a suitable application of Milne-Bhatnagar's characterization theorem about matrix inversions, we have found that Warnaar's elliptic matrix inversion can be further extended to the following general inversion theorem. 相似文献

强p除环上方阵的酉相似理论(Ⅲ) 总被引:4,自引:2,他引:2
In this third paper, the famous Schur theorem that an n× n complex matrix is unitary similar to an upper triangular matrix is generalized to the socalled ∑-lizable matrix over the strong p-division ring Ω, where ∑ is the algebraically closed extension field of the center of Ω , and ∑?Ω.The generalized Schur's identity and other results involving the general-ized normal matrix over Ω is obtained by using this generalized Schur theorem. 相似文献

In this paper,the main results are concluded in theorem 1 and theorem 4.Theorem 1 Let A,b be nxn matrix and re-dimensional vector respectively,which can be represented exactly in the computer.If W is a nonsingu-lar nXn matrix such that ||I-WA||<1 then for any algorithm the errors of the sulution of linear equations Ax - b (1) satisfy the following inequalities 相似文献

This paper derives a theorem of generalized singular value decomposition of quaternion matrices (QGSVD),studies the solution of general quaternion matrix equation AXB -CYD= E,and obtains quaternionic Roth's theorem. This paper also suggests sufficient and necessary conditions for the existence and uniqueness of solutions and explicit forms of the solutions of the equation. 相似文献
