Abstract In this thesis we introduce and study some notions of amenablilty of Banach algebrassuch as approximate amenability and approximate weak amenability We give a completecharacterization for approximate amenability of the group algebras We showthat there existapproximately amenable Banach algebras which are not amenable and of course weaklyamenable We finally show that for any p oo lP N with pontwise operations isnot amenable however it is weakly amenable I s i I I f if
