#### Weighted Hardy-Type Inequalities in Variable Exponent Morrey-Type Spaces

(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)

We study the p(.) -> q(.) boundedness of weighted multidimensional Hardy-type operators H-w(alpha(.)) and H-w(alpha(.)) of variable order alpha(x), with radial weight w(vertical bar x vertical bar), from a variable exponent locally generalized Morrey space L-p(.),L-phi(.)(R-n, w) to another L-q(.),L-psi(.)(R-n, w). The exponents are assumed to satisfy the decay condition at the origin and infinity. ...

#### Refinements of some limit hardy-Type Inequalities via Superquadracity

(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-03)

Refinements of some limit Hardy-type inequalities are derived and discussed using the concept of superquadracity. We also proved that all three constants appearing in the refined inequalities obtained are sharp. The natural turning point of our refined Hardy inequality is p=2 and for this case we have even equality.

#### Some inequalities for Cesàro means of double Vilenkin-Fourier series

(Journal article; Peer reviewed; Tidsskriftartikkel, 2018-12-19)

In this paper, we state and prove some new inequalities related to the rate of Lp approximation by Cesàro means of the quadratic partial sums of double Vilenkin–Fourier series of functions from Lp.

#### A NEW GENERALIZATION OF BOAS THEOREM FOR SOME LORENTZ SPACES Λq(ω)

(Journal article; Tidsskriftartikkel; Peer reviewed, 2018)

Let Λq( ω ), q > 0, denote the Lorentz space equipped with the (quasi) norm
[<i>MATHEMATICAL FORMULA</I>]
for a function f on [0,1] and with
ω
positive and equipped with some additional growth properties. A generalization of Boas theorem in the form of a two-sided inequality is obtained in the case of both general regular system [<i>MATHEMATICAL FORMULA</I>] and generalized Lorentz Λq( ω ) spaces

#### Weighted Hardy Operators in Complementary Morrey Spaces

#### On Some Power Means and Their Geometric Constructions

(Journal article; Peer reviewed; Tidsskriftartikkel, 2018)

The main aim of this paper is to further develop the recently initiatedresearch concerning geometric construction of some power means wherethe variables are appearing as line segments. It will be demonstratedthat the arithmetic mean, the harmonic mean and the quadratic meancan be constructed for any number of variables and that all power meanswhere the number of variables are n = 2m, m 1 2 N for all ...

#### Fejér and Hermite-Hadamard Type Inequalities for N-Quasiconvex Functions

(Journal article; Peer reviewed; Tidsskriftartikkel, 2017-12-28)

Some new extensions and re finements of Hermite – Hadamard and Fejer type inequalities for functions which are N -quasiconvex are derived and discussed.

#### Some new Two-Sided Inequalities concerning the Fourier Transform

(Journal article; Peer reviewed; Tidsskriftartikkel, 2017)

The classical Hausdorff-Young and Hardy-Littlewood-Stein inequalities do not hold for p > 2. In this paper we prove that if we restrict to net spaces we can even derive a two-sided estimate for all p > 1. In particular, this result generalizes a recent result by Liflyand E. and Tikhonov S. [7] (MR 2464253).

#### A new look at classical inequalities involving Banach lattice norms

(Journal article; Peer reviewed; Tidsskriftartikkel, 2017-12-08)

Some classical inequalities are known also in a more general form of Banach lattice norms and/or in continuous forms (i.e., for ‘continuous’ many functions are involved instead of finite many as in the classical situation). The main aim of this paper is to initiate a more consequent study of classical inequalities in this more general frame. We already here contribute by discussing some results of ...
