On Pompeiu-Chebyshev functional and its generalization

In this work, a generalization of Chebyshev functional is presented. New inequalities of Gruss type via Pompeiu's mean value theorem are established. Improvements of some old inequalities are proved. A generalization of pre-Gruss inequality is elaborated. Some remarks to further generalization of Chebyshev functional are presented. As applications, bounds for the reverse of CBS inequality are deduced. Hardy type inequalities on bounded real interval [a,b] under some other circumstances are introduced. Other related ramified inequalities for differentiable functions are also given.Comment: 30 page

Some properties of h-MN-convexity and Jensen's type inequalities

In this work, we introduce the class of $h$-${\rm{MN}}$-convex functions by generalizing the concept of ${\rm{MN}}$-convexity and combining it with $h$-convexity. Namely, Let $I,J$ be two intervals subset of $\left(0,\infty\right)$ such that $\left(0,1\right)\subseteq J$ and $\left[a,b\right]\subseteq I$. Consider a non-negative function $h: (0,\infty)\to \left(0,\infty\right)$ and let ${\rm{M}}:\left[0,1\right]\to \left[a,b\right]$ $(0<a<b)$ be a Mean function given by ${\rm{{\rm{M}}}}\left(t\right)={\rm{{\rm{M}}}}\left( {h(t);a,b} \right)$; where by ${\rm{{\rm{M}}}}\left( {h(t);a,b} \right)$ we mean one of the following functions: $A_h\left( {a,b} \right):=h\left( {1 - t} \right)a + h(t) b$, $G_h\left( {a,b} \right)=a^{h(1-t)} b^{h(t)}$ and $H_h\left( {a,b} \right):=\frac{ab}{h(t) a + h\left( {1 - t} \right)b} = \frac{1}{A_h\left( {\frac{1}{a},\frac{1}{b}} \right)}$; with the property that ${\rm{{\rm{M}}}}\left( {h(0);a,b} \right)=a$ and ${\rm{M}}\left( {h(1);a,b} \right)=b$. A function $f : I \to \left(0,\infty\right)$ is said to be $h$-${\rm{{\rm{MN}}}}$-convex (concave) if the inequality \begin{align*} f \left({\rm{M}}\left(t;x, y\right)\right) \le (\ge) \, {\rm{N}}\left(h(t);f (x), f (y)\right), \end{align*} holds for all $x,y \in I$ and $t\in [0,1]$, where M and N are two mean functions. In this way, nine classes of $h$-${\rm{MN}}$-convex functions are established and some of their analytic properties are explored and investigated. Characterizations of each type are given. Various Jensen's type inequalities and their converses are proved.Comment: 27 pages. Journal of Interdisciplinary Mathematics 201

On the generalized mixed Schwarz inequality

In this work, an extension of the generalized mixed Schwarz inequality is proved. A companion of the generalized mixed Schwarz inequality is established by merging both Cartesian and Polar decompositions of operators. Based on that some numerical radius inequalities are proved.Comment: 14 page

An Inequality of Simpson's type Via Quasi-Convex Mappings with Applications

In this paper, an inequality of Simpson type for quasi-convex mappings are proved. The constant in the classical Simpson's inequality is improved. Furthermore, the obtained bounds can be (much) better than some recently obtained bounds. Application to Simpson's quadrature rule is also given.Comment: 7 pages, no figur

In this work, operator version of Popoviciu's inequality for positive selfadjoint operators in Hilbert spaces under positive linear maps for superquadratic functions is proved. Analogously, using the same technique operator version of Popoviciu's inequality for convex functions is obtained. Some other related inequalities are also deduced.Comment: 11 page
