    Full text link
    In this paper, new sharp weighted generalizations of Ostrowski and generalized trapezoid type inequalities for the Riemann--Stieltjes integrals are proved. Several related inequalities are deduced and investigated. New Simpson's type inequalities for RS\mathcal{RS}--integral are pointed out.

    On Pompeiu-Chebyshev functional and its generalization

    Full text link
    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

    The Hermite-Hadamard inequality on hypercuboid

    Full text link
    Given any a:=(a1,a2,…,an){\bf{a}}: = \left( {a_1 ,a_2 , \ldots ,a_n } \right) and b:=(b1,b2,…,bn){\bf{b}}: = \left( {b_1 ,b_2 , \ldots ,b_n } \right) in Rn\mathbb{R}^n. The n\textbf{n}-fold convex function defined on [a,b]\left[ {{\bf{a}},{\bf{b}}} \right], a,b∈Rn{\bf{a}},{\bf{b}} \in \mathbb{R}^n with a<b{\bf{a}}<{\bf{b}} is a convex function in each variable separately. In this work we prove an inequality of Hermite-Hadamard type for n\textbf{n}-fold convex functions. Namely, we establish the inequality \begin{align*} f\left( {\frac{{{\bf{a}} + {\bf{b}}}}{2}} \right) \le \frac{1}{{{\bf{b}} - {\bf{a}}}}\int_{\bf{a}}^{\bf{b}} {f\left( {\bf{x}} \right)d{\bf{x}}} \le \frac{1}{{2^n }}\sum\limits_{\bf{c}} {f\left( {\bf{c}} \right)}, \end{align*} where βˆ‘cf(c):=βˆ‘ci∈{ai,bi}1≀i≀nf(c1,c2,…,cn)\sum\limits_{\bf{c}} {f\left( {\bf{c}} \right)} : = \sum\limits_{\mathop {c_i \in \left\{ {a_i ,b_i } \right\}}\limits_{1 \le i \le n} } {f\left( {c_1, c_2, \ldots ,c_n } \right)}. Some other related result are given.Comment: 12 page

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

    Full text link
    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

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

    Full text link
    In this work, we introduce the class of hh-MN{\rm{MN}}-convex functions by generalizing the concept of MN{\rm{MN}}-convexity and combining it with hh-convexity. Namely, Let I,JI,J be two intervals subset of (0,∞)\left(0,\infty\right) such that (0,1)βŠ†J\left(0,1\right)\subseteq J and [a,b]βŠ†I\left[a,b\right]\subseteq I. Consider a non-negative function h:(0,∞)β†’(0,∞)h: (0,\infty)\to \left(0,\infty\right) and let M:[0,1]β†’[a,b]{\rm{M}}:\left[0,1\right]\to \left[a,b\right] (0<a<b)(0<a<b) be a Mean function given by M(t)=M(h(t);a,b){\rm{{\rm{M}}}}\left(t\right)={\rm{{\rm{M}}}}\left( {h(t);a,b} \right); where by M(h(t);a,b){\rm{{\rm{M}}}}\left( {h(t);a,b} \right) we mean one of the following functions: Ah(a,b):=h(1βˆ’t)a+h(t)bA_h\left( {a,b} \right):=h\left( {1 - t} \right)a + h(t) b, Gh(a,b)=ah(1βˆ’t)bh(t)G_h\left( {a,b} \right)=a^{h(1-t)} b^{h(t)} and Hh(a,b):=abh(t)a+h(1βˆ’t)b=1Ah(1a,1b)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 M(h(0);a,b)=a{\rm{{\rm{M}}}}\left( {h(0);a,b} \right)=a and M(h(1);a,b)=b{\rm{M}}\left( {h(1);a,b} \right)=b. A function f:Iβ†’(0,∞)f : I \to \left(0,\infty\right) is said to be hh-MN{\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∈Ix,y \in I and t∈[0,1]t\in [0,1], where M and N are two mean functions. In this way, nine classes of hh-MN{\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
