    The authors introduce the notion of Drazin invertibility for range space linear relations and they prove that Drazin invertible linear relations with nonempty algebraic resolvent sets allow a Kato decomposition and that each B-Fredholm linear relation of index zero and with nonempty algebraic resolvent set is a sum of a closed Dravin invertible linear relation and a finite rank operator.
