摘　　要：讨论Banach空间中无界闭算子的线性斜投影广义逆的稳定性问题,利用T有界及广义Neumann引理给出了新的扰动定理.In this paper, we mainly study the Perturbation of oblique projection generalized inverse of closed linear operator, by T-bounded and the generalized Neumann lemma, we give a different Perturbation of oblique projection generalized inverse of closed linear operator.

关 键 词：BANACH空间 线性斜投影广义逆 扰动
