摘要：

Let X be an infinite-dimensional complex Banach space, and B(X) the algebra of all bounded linear operators on X. Given an integer n ≥ 1, we characterize all the bijective maps on B(X) preserving the difference of semi-Fredholm operators with nullity equal to n in both directions, and establish the structure of the given maps.
