PERTURBATIONS OF BANACH ALGEBRAS AND ALMOST MULTIPLICATIVE FUNCTIONALS

We discuss small deformations of Banach algebras and multiplicative functionals. We are particularly interested in properties that remain stable under such small deformations (perturbations). We survey the history of that area, provide some recent results, and discuss numerous open problems.
