Higher Order Riesz Transforms for Fourier-Bessel Expansions
, 2012 In this paper we investigate the Riesz transforms of order d ≥ 1, R d v, for Fourier-Bessel expansions. Weighted norm inequalities are proved for this operator.

Three two-dimensional Weyl steps in the circle problem II. The logarithmic Riesz mean for a class of arithmetic functions [PDF]
, 1999 1. Summary. In Part II we study arithmetic functions whose Dirichlet series satisfy a rather general type of functional equation. For the logarithmic Riesz mean of these functions we give a representation involving finite trigonometric sums. An essential

Some sequence spaces derived by Riesz mean in a real 2-normed space
, 2014 In the present paper, we introduce some new sequence spaces derived by Riesz mean and the notions of almost and strongly almost convergence in a real 2-normed space. Some topological properties of these spaces are investigated.

Riesz-McNaughton functions and Riesz MV-algebras of nonlinear functions
, 2015 We focus on Riesz MV-algebras, which are MV-algebras equipped with a multiplication by numbers in the real interval [0,1]. In analogy with a work in preparation for MV-algebras by the same authors, we consider for every integer n the Riesz MV-algebra of ...

Absolute summability factors for Cesàro and Riesz means
, 2022 Summary: In this paper we characterize the sets of summability factors \(({|C, 0|}_k, {|R, p_n|}_s)\) and \(({|R, p_n|}_k, {|C, 0|}_s)\), \(1 < k \leq s < \infty\), which also extends some known results.

Riesz-McNaughton functions and Riesz MV-algebras of nonlinear functions
, 2017 We focus on Riesz MV-algebras, which are MV-algebras equipped with a multiplication by numbers in the real interval . We consider for every integer n the Riesz MV-algebra of all continuous functions from the n-th power of to and the Riesz MV ...
