摘要 设H和K为复的无限维可分Hilbert空间.本文利用算子的几何结构着重研究了Hilbert空间H(?)K上的2×2算子矩阵的逆,给出了一些有意义的结果. Let H and K be separable complex infinite-dimensional Hilbert spaces. In this note, we primarily study inverses of 2 × 2 operator matrices on H+ K by utilizing the method of geometrical structure of operators, and obtain some meaningful results.
