| Research Abstract |
The author and coauthor succeeded in classifying commutative Banach algebras more closely by using the notion of quasi topology, which is originated from certain classes of Banach algebras introduced by the authors in 1990. In addition, the authors investigated classes for some concrete commutative Banach algebras. As applications, the authors solved certain stability problems and obtained several inequalities.
