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…
Theorem of coincidence of classes for a generalised shift operator
Nimete Sh. Berisha
In this paper, for a generalised shift operator introduced earlier, we prove theorem of coincidence of classes of functions defined by the order of best approximation by algebraica…
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…
Approximating classes of functions defined by a generalised modulus of smoothness
Faton M. Berisha, Nimete Sh. Berisha
In the present paper, we use a generalised shift operator in order to define a generalised modulus of smoothness. By its means, we define generalised Lipschitz classes of functions…
Approximating classes of functions defined by operators of differentiation or operators of generalised translation by means of algebraic polynomials
Nimete Sh. Berisha, Faton M. Berisha
In this paper, approximation by means of algebraic polynomials of classes of functions defined by a generalised modulus of smoothness of operators of differentiation of these funct…
