摘要
Let X be an infinite-dimensional real or complex Banach space,and B(X) the Banach algebra of all bounded linear operators on X.In this paper,given any non-negative integer n,we characterize the surjective additive maps on B(X) preserving Fredholm operators with fixed nullity or defect equal to n in both directions,and describe completely the structure of these maps.
