LetAandBbe Banach algebras with identity and letπ:A→Bbe a continuous homomorphism. We obtain conditions on the Hochschild cohomology ofAunder which perturbations of π are similar to π. We also show that ifAis a Banach algebra such thatH2(A,A) =H3(A,A) = 0, then perturbations of the multiplication ofAgive algebras isomorphic toA. We use our techniques to partially answer some problems of Kadison and Kastler on perturbations of operator algebras.
