研究了非线性算子的几种稳定性.采用算子论方法,提出了算子的ε-稳定性、一致稳定性、强一致稳定性和弱稳定性的定义,在此基础上研究了这些稳定性的一些充分条件、必要条件和充要条件.
The main purpose of this paper is to study several stabilities of nonlinear operators by using operator theoretic method. The definitions of ε-stability, uniform stability, strong uniform stability and weak stability of a nonlinear operator are given. Some sufficient, necessary, as well as necessary and sufficient conditions for these stabilities are obtained.
