A quantified Tauberian theorem for sequences

David Seifert (2015)

Studia Mathematica

Similarity:

The main result of this paper is a quantified version of Ingham's Tauberian theorem for bounded vector-valued sequences rather than functions. It gives an estimate on the rate of decay of such a sequence in terms of the behaviour of a certain boundary function, with the quality of the estimate depending on the degree of smoothness this boundary function is assumed to possess. The result is then used to give a new proof of the quantified Katznelson-Tzafriri theorem recently obtained by...

Tauberian operators on L 1 ( μ ) spaces

Manuel González, Antonio Martínez-Abejón (1997)

Studia Mathematica

Similarity:

We characterize tauberian operators T : L 1 ( μ ) Y in terms of the images of disjoint sequences and in terms of the image of the dyadic tree in L 1 [ 0 , 1 ] . As applications, we show that the class of tauberian operators is stable under small norm perturbations and that its perturbation class coincides with the class of all weakly precompact operators. Moreover, we prove that the second conjugate of a tauberian operator T : L 1 ( μ ) Y is also tauberian, and the induced operator T ̃ : L 1 ( μ ) * * / L 1 ( μ ) Y * * / Y is an isomorphism into. Also, we show that...
