设A,B是作用在Hilbert空间H上的两个有界线性算子,文中利用算子分块的技巧,在算子A值域闭的情况下讨论了算子方程AXA*=B解及其正解存在的充要条件并用算子矩阵的形式给出了它们的具体表示。
Let A, B be two bounded linear operators on a Hilbert space H. By using the block operator matrix, when the range of A is closed, the sufficient and necessary conditions for the existence of solutions and positive operator solutions of the operator equation AXA^*=B: B and the representation of the solutions are established.
