摘要 设H_1和H_2为可分Hilbert空间.对给定的算子A∈B(H_1)和C∈B(H_2,H_1),给出存在X∈B(H_1,H_2)和Y∈B(H_2),使得(XYAC)为可逆算子的充分必要条件. Let H_1 and H_2 be separable Hilbert spaces.For given operators A∈B(H_1) and C∈B(H_2,H_1),a necessary and sufficient condition is given for(XYAC) to be an invertible operator for some X∈B(H_1,H_2) and Y∈B(H_2).
