Let X be a complex Banach space and T a bounded linear operator on X. T is called a generalized Fredholm operator if T is relatively regular and if for some pseudo-inverse S of T the operator I - ST - T is Fredholm. The main result of this paper reads as follows: T is a generalized Fredholm operator if and only if T = T1 T2 , whereT1 is a Fredholm operator with jump j(Tl ) = 0 and T2 is a finite-dimensional nilpotent operator.
