摘要
利用广义正则点的概念和它的有关理论与方法,引进了广义预解式和广义扇形算子的概念.广义扇形算子拓广了扇形算子的概念,利用已知的扇形算子的稳定扰动,推广出广义扇形算子在A-有界下的无界扰动.
In this paper, we use the method of generalized regular point and its related theory and methods. The concept of the pre - generalized solutions and Generalized Sectorial operator are weU - defined. Generalized Sectorial operator extended the concept of Sectorial operator, we has known that Sectorial operator has the stability of perturbation, we explore the result that Generalized Sectorial operator has unbounded perturb under the A - bounded .
