On approximations by trigonometric polynomials of classes of functions defined by moduli of smoothness
Nimete Sh. Berisha, Faton M. Berisha, Mikhail K. Potapov +1
In this paper, we give a characterization of Nikol'ski\uı-Besov type classes of functions, given by integral representations of moduli of smoothness, in terms of series over the mo…
Some reverse -type inequalities involving certain quasi monotone sequences
Mikhail K. Potapov, Faton M. Berisha, Nimete Sh. Berisha +1
In this paper, we give some -type inequalities about sequences satisfying certain quasi monotone type properties. As special cases, reverse -type inequalities for non-neg…
Mixed Moduli of Smoothness in ,
M. K. Potapov, B. V. Simonov, S. Yu. Tikhonov
In this paper we survey recent developments over the last 25 years on the mixed fractional moduli of smoothness of periodic functions from , . In particular, the p…
