Abstract: In the first section of this paper the relationship between quasiaffine invertibility and invertibility of operators is investigated.For example, it is proved that if T is paranormal and has a right quasiaffine inverse, then T is invertible.In§2,several properties of operators which is inhe- rited by quasiaffine transforms(or right quasiaffine inverses)are given. In§3,the existence problem about the invariant subspaces of operators is discussed and some sufflicient conditions in terms of properties of quasia- ffine transforms of operators are obtained.
