摘要
利用算子矩阵分块的技巧,得到了Hilbert空间中算子的Moore-Penrose逆和Drazin逆的积分表示.给出了较为简洁的证明,同时将有限维的结论推广到无限维的情形.
By using the technique of operator matrix blocks, the integral representations of Moore-Penrose inverse and Drazin inverse of Hilbert space operators are obtained, which gives a new proof and the results on finite dimensional are extended into infi.nite dimensional situations.
