Identities, Approximate Identities and Topological Divisors of Zero in Banach Algebras

Rudi Brits, Melanie Hasse, Francois Schulz

In [3] S. J. Bhatt and H. V. Dedania exposed certain classes of Banach algebras in which every element is a topological divisor of zero. We identify a new (large) class of Banach a…
