Further improvements of Young inequality

open access: yes, 2017
We focus on the improvements for Young inequality. We give elementary proof for known results by Dragomir, and we give remarkable notes and some comparisons.

Some Remarks on the Trapezoid Rule In Numerical Integration [PDF]

open access: yes, 1999
In this paper, by the use of some classical results from the Theory of Inequalities, we point out quasi-trapezoid quadrature formulae for which the error of approximation is smaller than in the classical case.

New generalization of discrete Montgomery identity with applications [PDF]

open access: yes, 2016
In this paper, a discrete version of the well-known Montgomery's identity is generalized, and a refinement of an inequality derived by B.G. Pachpatte in 2007 is presented.

Decompositions of Nakano norms by ODE techniques

open access: yes, 2018
We study decompositions of Nakano type varying exponent Lebesgue norms and spaces. These function spaces are represented here in a natural way as tractable varying $\ell^p$ sums of projection bands. The main results involve embedding the varying Lebesgue

On isoperimetric inequalities with respect to infinite measures [PDF]

open access: yes, 2011
We study isoperimetric problems with respect to infinite measures on $R ^n$. In the case of the measure $\mu$ defined by $d\mu = e^{c|x|^2} dx$, $c\geq 0$, we prove that, among all sets with given $\mu-$measure, the ball centered at the origin has the ...

Abel-type inequalities, complex numbers and Gauss-Pólya type integral inequalities [PDF]

open access: yes, 1998
We obtain inequalities of Abel type but for nondecreasing sequences rather than the usual nonincreasing sequences. Striking complex analogues are presented. The inequalities on the real domain are used to derive new integral inequalities related to those

Symmetrization Inequalities for Composition Operators of Carathéodory Type [PDF]

open access: yes, 2017
Let F:(0, ∞) × [0, ∞) → R be a function of Carathéodory type. We establish the inequality $$ \int_{\mathbb{R}^{N}} F( | x |, u(x) ) dx \leq \int_{\mathbb{R}^{N} } F( | x |, u^{\ast}(x)) dx.
