Negative Powers of Contractions Having a Strong AA+ Spectrum
Moroccan Journal of Pure and Applied Analysis, 2023 Zarrabi proved in 1993 that if the spectrum of a contraction T on a Banach space is a countable subset of the unit circle 𝕋, and if limn→+∞log(‖T−n‖)n=0{\lim _{n \to + \infty }}{{\log \left( {\left\| {{T^{ - n}}} \right\|} \right)} \over {\sqrt n ...

Direct and strong converse inequalities for approximation with Fejér means
Demonstratio Mathematica, 2020 We present upper and lower estimates of the error of approximation of periodic functions by Fejér means in the Lebesgue spaces L2πp{L}_{2{\pi }}^{p}. The estimates are given in terms of a K-functional for 1≤p≤∞1\le p\le \infty and in terms of the first ...

Maximal estimates for strong arithmetic means of Fourier series
Advanced Nonlinear StudiesIt is well-understood that partial sums of Fourier series for L 1 functions don’t necessarily converge to the original function in the pointwise-almost everywhere sense.

Characterization of Blackman Kernels as Approximate Identities.
, 2001 We characterize completely when a Blackman kernel is an approximate identity with respect to L p (T ) , 1 p ! 1 , or C(T ) , with T = fz 2 C : jzj = 1g . 1991 Mathematics Subject Classification. 42A20 Key words and phrases.
