Voronovskaja’s Theorem in Terms of Weighted Modulus of Continuity

Developments in Mathematics, 2017
Let E be a subspace of C[0, ∞) which contains the polynomials and L n : E → C[0, ∞) be a sequence of linear positive operators. The weighted modulus of continuity, considered by Acar–Aral–Rasa in [7] is denoted by \(\Omega (f;\delta )\) and given by $$\displaystyle{\Omega (f;\delta ) =\sup _{0\leq ...

Singular integral operators in weighted spaces of continuous functions with non-equilibrated continuity modulus

Mathematische Nachrichten, 2006
AbstractWe show that singular integral operators with piecewise continuous coefficients may gain massive spectra when considered in weighted spaces of continuous functions with a prescribed continuity modulus (generalized Hölder spaces Hω (Γ, ρ )), a fact known for example for Lebesgue spaces Lp (Γ, ρ ) in the case of general Muckenhoupt weights ρ or ...

Characterization of relatively compact sets in weighted Lebesgue spaces by weighted modulus of continuity and application

In this paper we consider a weighted modulus of continuity in weighted Lebesgue spaces. We proved that the modulus of continuity is well defined in weighted Lebesgue spaces and has all the properties of usual modulus of continuity. Also, we study relatively compact sets in weighted Lebesgue spaces.
