【Abstract】 Some properties of operator Fredholm sequences are discussed. As a generalization of results for a single Fredholm as semi-Fredholm operator,several equivalent conditions for uniformly convergent sequences of bounded linear operators to be (upper-semi,lower-semi) operator Fredholm sequences are obtained.更多还原
