\section{Introduction and preliminaries}

In this section, we will present definitions and some results used
in this paper.

Let \ $f:I\subseteq
%TCIMACRO{\U{211d} }%
%BeginExpansion
\mathbb{R}
%EndExpansion
\rightarrow
%TCIMACRO{\U{211d} }%

$ be a convex mapping defined on the interval $I$\ of real numbers and $%
a,b\in I$, with $a<b$. The following double inequalities:%
\begin{equation*}
f\left( \frac{a+b}{2}\right) \leq \frac{1}{b-a}\int_{a}^{b}f\left(
x\right) dx\leq \frac{f\left( a\right) +f\left( b\right) }{2}
\end{equation*}%
hold. This double inequality is known in the literature as the
Hermite-Hadamard inequality for convex functions (see
\cite{bai}-\cite{tnc}).

\begin{definition}
Let $I$ be an interval in $%
%TCIMACRO{\U{211d} }%
%BeginExpansion
\mathbb{R}
%EndExpansion
.$ Then $f:I\rightarrow
%TCIMACRO{\U{211d} }%

\mathbb{R}
%EndExpansion
,$ $\emptyset \neq I\subseteq
%TCIMACRO{\U{211d} }%

%EndExpansion
$\ is said to be convex if
\begin{equation}
f\left( tx+\left( 1-t\right) y\right) \leq tf\left( x\right)
+\left( 1-t\right) f\left( y\right) .  \label{7}
\end{equation}%
for all $x,y\in I$ and $t\in \left[ 0,1\right] $.
\end{definition}

The concepts of $\alpha $-, $m$- and $\left( \alpha ,m\right) $%
-logarithmically convex functions were introduced as follows.

\begin{definition}
\cite{bai}\label{d} A function $f:[0,b]\rightarrow (0,\infty )$ is
said to
be $m$-logarithmically convex if the inequality%
\begin{equation}
f\left( tx+m\left( 1-t\right) y\right) \leq \left[ f\left(
x\right) \right] ^{t}\left[ f\left( y\right) \right] ^{m\left(
1-t\right) }  \label{d1}
\end{equation}%
holds for all $x,y\in \lbrack 0,b]$, $m\in (0,1]$, and $t\in
\lbrack 0,1]$.
\end{definition}

Obviously, if putting $m=1$ in Definition \ref{d}, then $f$ is
just the ordinary logarithmically convex on $\left[ 0,b\right] $.

\begin{definition}
\cite{tnc}\label{ddd} A function $f:[0,b]\rightarrow (0,\infty )$
is said to
be $\alpha $-logarithmically convex if%
\begin{equation}
f\left( tx+\left( 1-t\right) y\right) \leq \left[ f\left( x\right)
\right] ^{t^{\alpha }}\left[ f\left( y\right) \right] ^{\left(
1-t^{\alpha }\right) }
\end{equation}%
holds for all $x,y\in \lbrack 0,b]$, $\alpha \in \left( 0,1\right] $ and $%
t\in \lbrack 0,1]$.
\end{definition}

Clearly, when taking $\alpha =1$ in Definition \ref{ddd}, then $f$
becomes the ordinary logarithmically convex on $\left[ 0,b\right]
$.

\begin{definition}
\cite{bai}\label{dd} A function $f:[0,b]\rightarrow (0,\infty )$
is said to
be $\left( \alpha ,m\right) $-logarithmically convex if%
\begin{equation}
f\left( tx+m\left( 1-t\right) y\right) \leq \left[ f\left(
x\right) \right] ^{t^{\alpha }}\left[ f\left( y\right) \right]
^{m\left( 1-t^{\alpha }\right) }  \label{d2}
\end{equation}%
holds for all $x,y\in \lbrack 0,b]$, $\left( \alpha ,m\right) \in \left( 0,1%
\right] \times \left( 0,1\right] ,$ and $t\in \lbrack 0,1]$.
\end{definition}

Clearly, when taking $\alpha =1$ in Definition \ref{dd}, then $f$
becomes the standard $m$-logarithmically convex function on
$\left[ 0,b\right] $,
and, when taking $m=1$ in Definition \ref{dd}, then $f$ becomes the $\alpha $%
-logarithmically convex function on $\left[ 0,b\right] $.

In \cite{dr3}, the following theorem which was obtained by
Dragomir and Agarwal contains the Hermite-Hadamard type integral
inequality.

\begin{theorem}
\cite[Theorem 2.2]{dr3} Let $f:I\subseteq
%TCIMACRO{\U{211d} }%

$ be a differentiable mapping on $I^{\circ }$, the interior of
$I$, $a,b\in
I^{\circ }$ with $a<b$. If $|f^{\prime }\left( x\right) |$ is convex on $%
[a,b]$, then%
\begin{equation}
\left\vert \frac{f\left( a\right) +f\left( b\right) }{2}-\frac{1}{b-a}%
\int_{a}^{b}f\left( x\right) dx\right\vert \leq \frac{\left(
b-a\right) \left( \left\vert f^{\prime }\left( a\right)
\right\vert +\left\vert f^{\prime }\left( b\right) \right\vert
\right) }{8}.  \label{109}
\end{equation}
\end{theorem}

\begin{theorem}
\cite[Theorem 2.3]{dr3} Let $f:I\subseteq
%TCIMACRO{\U{211d} }%

\rightarrow
%TCIMACRO{\U{211d} }%
%BeginExpansion
\mathbb{R}

$ be a differentiable mapping on $I^{\circ }$, $a,b\in I^{\circ }$
with $a<b, $ and $p>1$. If the new mapping $|f^{\prime }\left(
x\right) |^{p/p-1}$ is
convex on $[a,b]$, then%
\begin{eqnarray}
&&\left\vert \frac{f\left( a\right) +f\left( b\right) }{2}-\frac{1}{b-a}%
\int_{a}^{b}f\left( x\right) dx\right\vert  \\
&\leq &\frac{b-a}{2\left( p+1\right) ^{1/p}}\left[
\frac{\left\vert f^{\prime }\left( a\right) \right\vert ^{p/\left(
p-1\right) }+\left\vert f^{\prime }\left( b\right) \right\vert
^{p/\left( p-1\right) }}{2}\right] ^{\left( p-1\right) /p}.
\notag
\end{eqnarray}
\end{theorem}

The aim of this paper is to establish some integral inequalities
of
Hermite-Hadamard type for $\alpha $-, $m$-$,$ $\left( \alpha ,m\right) $%
-logarithmically convex functions.



\section{Hadamard Type Inequalities}

In order to prove our main theorems, we need the following lemma
\cite{lmmm}.

\begin{lemma}
\label{l1}\cite{lmmm} Let $f:\ I\subset
%TCIMACRO{\U{211d} }%
%BeginExpansion
\mathbb{R}
%EndExpansion
\rightarrow
%TCIMACRO{\U{211d} }%
%BeginExpansion
\mathbb{R}
%EndExpansion
$ be a differentiable mapping on $I^{\circ }$\textit{, }$a,b\in $
$I^{\circ } $ with $a$ $<$ $b$. If $f^{\prime }\in $ $L\left[
a,b\right] ,$ then the following equality holds:
\begin{eqnarray}
&&\frac{f\left( a\right) +f\left( b\right) }{2}-\frac{1}{b-a}%
\int_{a}^{b}f\left( x\right) dx  \label{a} \\
&=&\frac{b-a}{2}\int_{0}^{1}\int_{0}^{1}\left[ f^{\prime }\left(
ta+\left( 1-t\right) b\right) -f^{\prime }\left( sa+\left(
1-s\right) b\right) \right] \left( s-t\right) dtds.  \notag
\end{eqnarray}
\end{lemma}

A simple proof of this equality can be also done integrating by
parts in the right hand side (see \cite{lmmm}).

The next theorems gives a new result of the upper Hermite-Hadamard
inequality for $\alpha $-, $m$-, $\left( \alpha ,m\right)
$-logarithmically convex functions.

\begin{theorem}
\label{t1}Let$\ I\supset \left[ 0,\infty \right) $ be an open
interval and let $f:\ I\rightarrow \left( 0,\infty \right) $ be a
differentiable function on $I$ such that $f^{\prime }\in L\left(
a,b\right) $ for $0\leq a<b<\infty . $ If $\left\vert f^{\prime
}\left( x\right) \right\vert $ is $\left( \alpha ,m\right)
$-logarithmically convex on $\left[ 0,\frac{b}{m}\right] $ for
$\left( \alpha ,m\right) \in \left( 0,1\right] ^{2},$ then
\begin{eqnarray}
&&\left\vert \frac{f\left( a\right) +f\left( b\right) }{2}-\frac{1}{b-a}%
\int_{a}^{b}f\left( x\right) dx\right\vert \\
&\leq &\left\{
\begin{array}{cc}
\frac{\left( b-a\right) }{3}\left\vert f^{\prime }\left(
\frac{b}{m}\right) \right\vert ^{m},\text{ \ \ \ \ \ \ \ \ \ \ \ \
\ \ \ \ \ \ \ \ \ \ \ \ \ \ }
& \eta =1 \\
\frac{\left( b-a\right) }{2}\left\vert f^{\prime }\left(
\frac{b}{m}\right) \right\vert ^{m}\frac{-\alpha ^{2}\ln ^{2}\eta
-2\alpha \ln \eta +2\eta
^{\alpha }-2}{\alpha ^{3}\ln ^{3}\eta }, & \eta <1%
\end{array}%
\right.  \notag
\end{eqnarray}%
where $\eta =\left\vert f^{\prime }\left( a\right) \right\vert
/\left\vert f^{\prime }\left( \frac{b}{m}\right) \right\vert
^{m}.$
\end{theorem}

\begin{proof}
By Lemma \ref{l1} and since $\left\vert f^{\prime }\right\vert $ is an $%
\left( \alpha ,m\right) $-logarithmically convex on $\left[ 0,\frac{b}{m}%
\right] $, then we have%
\begin{eqnarray*}
&&\left\vert \frac{f\left( a\right) +f\left( b\right) }{2}-\frac{1}{b-a}%
\int_{a}^{b}f\left( x\right) dx\right\vert \\
&\leq &\frac{b-a}{2}\int_{0}^{1}\int_{0}^{1}\left\vert \left(
f^{\prime }\left( ta+\left( 1-t\right) b\right) \right) -\left(
f^{\prime }\left( sa+\left( 1-s\right) b\right) \right)
\right\vert \left\vert s-t\right\vert
dtds \\
&\leq &\frac{b-a}{2}\left[ \int_{0}^{1}\int_{0}^{1}\left\vert
s-t\right\vert \left\vert f^{\prime }\left( a\right) \right\vert
^{t^{\alpha }}\left\vert f^{\prime }\left( \frac{b}{m}\right)
\right\vert ^{m\left( 1-t^{\alpha
}\right) }dtds\right] \\
&&+\frac{b-a}{2}\left[ \int_{0}^{1}\int_{0}^{1}\left\vert
s-t\right\vert \left\vert f^{\prime }\left( a\right) \right\vert
^{s^{\alpha }}\left\vert f^{\prime }\left( \frac{b}{m}\right)
\right\vert ^{m\left( 1-s^{\alpha }\right) }dtds\right]
\end{eqnarray*}%
Let $0<k\leq 1,$ $0\leq m\leq 1,$ and $0<n\leq 1$. Then%
\begin{equation}
k^{m^{n}}\leq k^{nm}.  \label{1}
\end{equation}
When $\eta =1,$ by (\ref{1}), we get%
\begin{eqnarray*}
&&\left\vert \frac{f\left( a\right) +f\left( b\right) }{2}-\frac{1}{b-a}%
\int_{a}^{b}f\left( x\right) dx\right\vert \\
&\leq &\frac{b-a}{2}\left\vert f^{\prime }\left(
\frac{b}{m}\right) \right\vert ^{m}\left[
\int_{0}^{1}\int_{0}^{1}\left\vert s-t\right\vert
dtds+\int_{0}^{1}\int_{0}^{1}\left\vert s-t\right\vert dtds\right] \\
&=&\frac{b-a}{3}\left\vert f^{\prime }\left( \frac{b}{m}\right)
\right\vert ^{m}
\end{eqnarray*}%
When $0<\eta <1,$ by (\ref{1}), we get
\begin{eqnarray*}
&&\left\vert \frac{f\left( a\right) +f\left( b\right) }{2}-\frac{1}{b-a}%
\int_{a}^{b}f\left( x\right) dx\right\vert \\
&\leq &\frac{b-a}{2}\left\vert f^{\prime }\left(
\frac{b}{m}\right) \right\vert ^{m}\left[
\int_{0}^{1}\int_{0}^{1}\left\vert s-t\right\vert \eta ^{\alpha
t}dtds+\int_{0}^{1}\int_{0}^{1}\left\vert s-t\right\vert \eta
^{\alpha s}dtds\right] \\
&=&\frac{b-a}{2}\left\vert f^{\prime }\left( \frac{b}{m}\right)
\right\vert ^{m}\left[ \frac{-\alpha ^{2}\ln ^{2}\eta -2\alpha \ln
\eta +4\eta ^{\alpha
}+\alpha ^{2}\eta ^{\alpha }\ln ^{2}\eta -2\alpha \eta ^{\alpha }\ln \eta -4%
}{2\alpha ^{3}\ln ^{3}\eta }\right. \\
&&+\left. \frac{-\alpha \ln \eta +2\eta ^{\alpha }-\alpha \eta
^{\alpha }\ln \eta -2}{2\alpha ^{2}\ln ^{2}\eta }\right]
\end{eqnarray*}%
which completes the proof.
\end{proof}

\begin{corollary}
Let$\ I\supset \left[ 0,\infty \right) $ be an open interval and
let $f:\ I\rightarrow \left( 0,\infty \right) $ be a
differentiable function on $I$
such that $f^{\prime }\in L\left( a,b\right) $ for $0\leq a<b<\infty .$ If $%
\left\vert f^{\prime }\left( x\right) \right\vert $ is
$m$-logarithmically
convex on $\left[ 0,\frac{b}{m}\right] $ for $m\in \left( 0,1\right] $, then
\begin{equation*}

\right.
\end{equation*}%
where $\eta $ is same as Theorem \ref{t1}.

Let$\ I\supset \left[ 0,\infty \right) $ be an open interval and

\left\vert f^{\prime }\left( x\right) \right\vert $is $\alpha $%
-logarithmically convex on $\left[ 0,b\right] $ for $\alpha \in \left( 0,1%

\end{equation}%
where $\eta =\left\vert f^{\prime }\left( a\right) \right\vert
/\left\vert f^{\prime }\left( b\right) \right\vert .$
\end{corollary}

\begin{theorem}
\label{t2}Let$\ I\supset \left[ 0,\infty \right) $ be an open
interval and let $f:\ I\rightarrow \left( 0,\infty \right) $ be a
differentiable function on $I$ such that $f^{\prime }\in L\left(
a,b\right) $ for $0\leq a<b<\infty
. $ If $\left\vert f^{\prime }\left( x\right) \right\vert ^{q}$ is an $%

p,q>1 $ with $\frac{1}{p}+\frac{1}{q}=1,$ then%
\begin{eqnarray}

\int_{a}^{b}f\left( x\right) dx\right\vert \\
&\leq &\left\{

\end{array}%
\right.  \notag
\end{eqnarray}%
where $\eta \left( \alpha ,\alpha \right) $ is same as Theorem
\ref{t1}.
\end{theorem}

\begin{proof}
Since $\left\vert f^{\prime }\right\vert ^{q}$ is an $\left(
\alpha ,m\right) $-logarithmically convex on $\left[
0,\frac{b}{m}\right] $, from
Lemma \ref{l1} and the well known H\"{o}lder inequality, we have%

\end{eqnarray}%
If $\ \eta =1,$ by (\ref{1}), we obtain%
