We study certain commutative regular semisimple Banach algebras which we call hyper-Tauberian algebras. We first show that they form a subclass of weakly amenable Tauberian algebras. Then we investigate the basic and hereditary properties of them. Moreover, we show that if A is a hyper-Tauberian algebra, then the linear space of bounded derivations from A into any Banach A-bimodule is reflexive. We apply these results to the Figà–Talamanca–Herz algebra A p ( G ) of a locally compact group G for p ∈ ( 1 , ∞ ) . We show that A p ( G ) is hyper-Tauberian if the principal component of G is abelian. Finally, by considering the quantization of these results, we show that for any locally compact group G, A p ( G ) , equipped with an appropriate operator space structure, is a quantized hyper-Tauberian algebra. This, in particular, implies that A p ( G ) is operator weakly amenable.
