Mond-Pečarić Method in Operator Inequalities

Inequalities for bounded selfadjoint operators on a Hilbert space

The authors first state the fundamental properties of bounded linear operators on a Hilbert space. Then they describe how Jensen's type inequalities develop in the field of operator inequalities. The Mond-Pečarić method for convex functions has outlined a more complete picture of converses of Jensen's inequality in the field of operator inequalities. The better part of the book is devoted to presenting results by using said method.

Euler integral identity, quadrature formulae and error estimations

From the point of view of inequality theory

The book contains generalizations of many classical quadrature formulas such as Simpson, dual Simpson, Maclaurin, Gauss, Lobatto and Radau. The specific feature of this book is that a unique method is used. This method is based on the Euler integral identities expressing expansion of a function in Bernoulli polynomials, proved by V. I. Krylov as a generalization of the first and the second Euler-Maclaurin sum formula. Mostly as error estimates, the book presents some aspects of generalizations, refinements and variants of four famous inequalities: the Hermite-Hadamard, the Ostrowski, the Bullen and the Iyengar inequality, which is an exception. Although related to the Hermite-Hadamard inequality in the same way as the Ostrowski inequality, Iyengar type inequalities are, it seems, beyond the reach of the method presented in this book. This is the reason why generalizations of the Iyengar inequality are given in the Addendum.

Recent Advances in Hilbert-type Inequalities

A unified treatment of Hilbert-type inequalities

Recent Advances in Hilbert-type inequalities is a crown of decennial research of several authors in the theory of Hilbert-type inequalities. The book is based on some thirty significant papers dealing with this problem area, published in the course of the last ten years. The present book provides a unified approach to Hilbert-type inequalities, the main results are established in general sigma finite measure spaces, with general kernels and weight functions. A special emphasis has been dedicated to establishing diverse methods for improving original Hilbert-type inequalities. Diverse generalizations, refinements and applications of Hilbert-type inequalities are presented.

Recent Developments of Mond-Pečarić Method in Operator Inequalities

Inequalities for bounded selfadjoint operators on a Hilbert space, II

The authors first state the fundamental properties of bounded linear operators on a Hilbert space. Then they tell the history of the Kantorovich inequality, and describe how the Kantorovich inequality develops in the field of operator inequalities. The Mond- Pečarić method for convex functions has outlined a more complete picture of that inequality in the field of operator inequalities. The better part of the book is devoted to presenting many new results by using said method. In such context, the generalization and improvement of many famous inequalities are presented.

General Integral Identities and Related Inequalities

Arising from Weighted Montgomery Identity

The main objective of this book is to expose some recent research in the theory of weighted integral and discrete inequalities of Ostrowski type, with emphasis on its various useful applications such as generalizations of classical numerical quadrature rules. Obtained results generalize, refine, unify or sharpen some well-known or previously obtained inequalities. General identities from which the related inequalities are deduced in this book are various kinds of different generalizations of Montgomery identity and Euler integral formula which express expansion of a function in terms of Bernoulli polynomials. This book is intended for researchers in the field of mathematical inequalities, but it can also be used by graduate students and advanced undergraduates.

Inequalities of Hardy and Jensen

New Hardy type inequalities with general kernels

In this book some general aspects of generalizations, refinements, and variants
of famous Hardy's inequality are presented. An integral operator with general non-
negative kernel on measure spaces with positive *σ*-finite measure is considered and
some new weighted Hardy type inequalities for convex functions and refinements of
weighted Hardy type inequalities for superquadratic functions are obtained. Moreover,
some refinements of weighted Hardy type inequalities for convex functions and
some new refinements of discrete Hardy type inequalities are given. Furthermore,
improvements and reverses of new weighted Hardy type inequalities with integral
operators are stated and proved. By using the concept of the subdifferential of a
convex function, the general Boas-type inequality is given and some new inequalities
for superquadratic and subquadratic functions as well as for functions which can be
bounded by non-negative convex or superquadratic function are obtained. The Boas
functional and related inequality allow us to adjust Lagrange and Cauchy mean value
theorems to the context and in that way define a new class of two-parametric means of
the Cauchy-type. We also give some interesting, one-dimensional and multidimensional,
examples related to balls and cones in *R ^{n}*.

Steffensen's and Related Inequalities

A Comprehensive Survey and Recent Advances

Since its appearance in 1918, Steffensen’s inequality is the subject of investigation by numerous mathematicians. The book is devoted to generalizations and refinements of Steffensen’s inequality and its connection to other inequalities, such as Gauss’, Jensen-Steffensen’s, Hölder’s and Iyengar’s inequality. A brief historical overview and a survey of weaker conditions for inverse Steffensen’s inequality is given. The book also contains Lp generalizations, generalizations for convex functions, refinements and sharpened versions, multidimensional generalizations and measure spaces generalizations of Steffensen’s inequality.

Combinatorial Improvements of Jensen's Inequality

Classical and New Refinements of Jensen's Inequality with Applications

The present book aims to collect results about refinements of Jensen’s inequality; to provide methods of constructing refinements of Jensen’s inequality, with emphasis on the combinatorial improvements; conformation of old results from new points of view and insights; to define quasi-arithmetic and mixed symmetric means corresponding to the introduced refinements; to generate Cauchy means by using the refinements and the notion of exponential convexity; to study the monotonicity all of these means. The presented overview yields numerous possibilities for further exploration.

Jensen Inequalities on Time Scales

Theory and Applications

This book summarizes very recent research related to Jensen-type inequalities on time scales. Many of the present results are proved via the theory of isotonic linear functionals. The book combines three areas of classical and active current research: classical inequalities in analysis, dynamic equations on time scales and isotonic linear functionals.

Weighted Energy Estimates for Convex Functions, Convex Vectors and Subsolution of Partial Differential Equation

Selected topics in reverse Poincare type inequalities

The regularity theory for solutions of certain parabolic partial differential equations is a well developed topic, but when it comes to subsolutions and supersolutions a lot remains to be done. The reverse Poincare type inequalities represent an important tool in the study of qualitative properties of solution of elliptic as well as parabolic partial differential equations.
