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 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}*.

Analytical Inequalities for Fractional Calculus Operators and the Mittag-Leffler Function

Applications of integral operators containing an extended generalized Mittag-Leffler function in the kernel

Inequalities which involve integrals of functions and their derivatives occupy a central place in mathematical analysis and its applications. Fractional differentiation inequalities have applications to fractional differential equations; the most important ones are in establishing uniqueness of the solution of initial problems and giving upper bounds to their solutions. These applications have motivated many researchers in the field of integral inequalities to investigate certain extensions and generalizations using different fractional differential and integral operators. As a solution of fractional order differential or integral equations, the Mittag-Leffler function with its generalizations appears.

Edmundson-Lah-Ribarič Type Inequalities

Reverses of the Edmundson-Lah-Ribarič Inequality with Applications to Classical Inequalities

This book is based on several recent research papers on the subject of Jensen’s inequality, its converses and their variants, with special emphasis on the Edmundson-Lah Ribarič inequality in different settings and under various conditions. In the first chapter we will show some difference type converses of the mentioned inequalities for positive linear functionals, together with their refinements, improvements and applications to many famous classical inequalities. In the second chapter different classes of inequalities of vii the Jensen and Edmundson-Lah-Ribarič type for functions with bounded second order divided differences, Lipschitzian functions and 3-convex functions are derived. Also, several representations of the left side in the Edmundson-Lah-Ribarič inequality via Hermite’s interpolating polynomial in terms of divided differences are given and used for obtaining inequalities for the class of n-convex functions. Third chapter is dedicated to estimates for the Csisz´ar f -divergence functional and generalization of the f-divergence functional for different classes of functions via results from the previous two chapters. Application to Zipf and Zipf-Mandelbrot law is also given. In the fourth chapter we give difference type converses of the Jensen and Edmundson-Lah-Ribarič operator inequality for a unital field of positive linear mappings between C*-algebras of operators in compact Hausdorff space and their further refinements and improvements. Several mutual bounds for the operator version of the Jensen and Edmundson-Lah-Ribarič inequality which hold for the classes of bounded real-valued functions, Lipschitzian functions and n-convex functions are also given. In the fifth chapter we show some converses of Ando’s and Davis-Choi’s inequality of different types, as well as the Edmundson-Lah-Ribarič inequality and its difference type converse for positive linear mappings. Some results are extended to the class of n-convex functions. Difference type converse for solidarities and connections are also given. In the sixth chapter, some converses of the Jensen and Edmundson-Lah-Ribarič inequality in terms of time scale calculus are proved together with new refinements of those converse relations with respect to the multiple Lebesgue delta integral for convex functions. In the last chapter we give a short historical comment on the connection between the Edmundson-Madansky and the Lah-Ribariˇc inequality, and an overview of some already known results. Also we give a Levinson’s type generalization of the Edmundson-Lah-Ribarič inequality for a class of functions which contains the class of 3-convex functions, and analogous inequalities for the operator inequality in the Hilbert space and the scalar product of Hilbert space operators.

New Developments for Jensen and Lah-Ribarič Inequalities

Current Trends in Convex Analysis

This book is divided in three chapters. The first chapter gives refinements of the Jensen and the Lah-Ribarič inequality, for their discrete and integral forms. The technique used in proving these refinements can be found in the proof of the Jensen-Boas inequality. Using this results, a refinement of the integral Hölder and discrete Hölder inequality, and refinements of some inequalities for power means and quasi arithmetic means are obtained. Also from the refinement of the integral forms we get a refinement of the famous Hermite-Hadamard inequality. As applications of these refinements, in the last part of the chapter we give some interesting estimates for the Csisz´ar divergence (discrete and integral case), and for the discrete case we also consider the Zipf-Mandelbrot law. In Chapter 2, we consider a generalization of the Jensen-McShane inequality for normalized positive isotonic linear functional and convex (concave) functions defined on a rectangle. We present the sequences of inequalities involving McShane generalization of Jensen’s inequality. As applications of these inequalities, for various choices of the functional F, we present extensions of known inequalities: the Diaz-Metcalf type inequalities for bounded random variables, the Fey´er and the Lupa¸s type inequalities for a function of two variables and inequalities of the Petrovi´c type for two non-negative real n-tuples. A conversion of the Jensen-McShane inequality is obtained by the two-variables function. Under special conditions, the Gheorghiu-type inequality is proved. The last chapter is dedicated to the recently introduced class of (h,g;m)-convex functions, which unifies a certain range of convexity, thus allowing the generalizations of known results. For this class, we present several types of inequalities such as Hermite-Hadamard, Fejér, Lah-Ribarič and Jensen, which generalize and extend corresponding inequalities. From Lah-Ribarič type inequalities for (h,g;m)-convex functions we obtain inequalities of Giaccardi, Popoviciu and Petrović. We also point out some special refined results. At the end, we use fractional calculus to obtain fractional version of the Hermite-Hadamard inequality, involving Riemann-Liouville fractional integral operators, which contain extended generalized Mittag-Leffler functions as their kernel. As an application, the upper bounds of fractional integral operators for (h,g;m)-convex functions are given.

Extension, Dimension and Shape

The following is a collection of notes that emanated from a topology seminar conducted at the University of Zagreb during the fall of 1999 and the spring of 2000. This work contains a compilation of a portion of the research that has been done in the areas of extension theory, dimension theory, and connections between these two and shape theory. The main emphasis will be on the former two, but we shall include the third because of the way it has been intertwined with the others. When we found it possible, we made steps to improve the efficiency and clarity of what had been published previously in the literature relative to these subjects. So the reader might even find some new results in the following even though it was not the authors’ intent to produce a research article. This writing is not meant to be a historical presentation, but to set the tone, we have provided, in the ensuing paragraphs, at least a rudimentary scan of the events leading to our survey.

An Adventure in the Realm of Topology

Topology, also known as rubber sheet geometry, studies the shape of objects up to continuous deformations that can be continuously undone. Supported by his experience, not only in university teaching, but also in training teachers, professor Moslehian offers us a textbook, with quite advanced topics and many activities, that will certainly engage students, and create an interest in new concepts. The book contains many activities, nicely illustrated, and these will develop the natural tendency in teenagers to be explorers. For instance, in one activity the reader is asked to use a marker to draw a circle, a triangle, and a square on an uninflated balloon and then inflate the balloon. Then the reader is asked to explain why the resulting shapes are topologically equivalent to the original ones. The book also contains many challenging topics: four-dimensional spaces, knot theory, and fractals, to mention a few. The formal study of these topics requires many prerequisites. However, with his ample experience, Professor Moslehian manages to communicate them without technicalities, engaging the curious students in a pleasant ludic journey. The book will appeal to anyone interested in geometry and can be regarded as a great contribution to the popularization of mathematics.
