摘要
设R为一个含幺环,应用矩阵的{1,2}逆(存在的前提下),本文得到R上矩阵方程AXB+CYD=E有解的充要条件以及一般解的公式。
Let R be a ring with identity, by using the {1, 2} inverses of matrices (if there exist), this paper obtains the necessary and sufficient conditions for existence of asolution and the explicit formulas of the general solution to the matrix equation AXB+CYD=E over R , and extends the well know Roth's equivalence theorem
