Let T and S be two bounded linear operators from Banach spaces X into Y, Ž . and suppose that T is Fredholm and dim N T y S is constant in a neighborhood Ž . Ž . of s 0. Let d T; S be the supremum of all r ) 0 such that dim N T y S and Ž . < < codim R T y S are constant for all withr. It is a conseq
