Solved and unsolved problems in generalized notions of amenability for Banach algebras

Volume 91 / 2010

Yong Zhang Banach Center Publications 91 (2010), 441-454 MSC: Primary 46H20; Secondary 43A20. DOI: 10.4064/bc91-0-26


We survey the recent investigations on approximate amenability//contractibility and pseudo-amenability/contractibility for Banach algebras. We will discuss the core problems concerning these notions and address the significance of any solutions to them to the development of the field. A few new results are also included.
