Research paper
<p>Let $G$ be a group with identity $e$ and $R$ be a commutative<br>
$G$-graded ring with nonzero unity $1$. In this article, we introduce the concept<br>
of graded $r$-ideals. A proper graded ideal $P$ of a graded ring $R$ is said to be<br>
graded $r$-ideal if whenever $a, bin h(R)$ such that $abin P$ and $Ann(a)={0}$,<br>
then $bin P$. We study and investigate the behavior of graded $r$-ideals to introduce<br>
several results. We introduced several characterizations for graded $r$-ideals;<br>
we proved that $P$ is a graded $r$-ideal of $R$ if and only if $aP=aRbigcap P$<br>
for all $ain h(R)$ with $Ann(a)={0}$. Also, $P$ is a graded $r$-ideal of $R$<br>
if and only if $P=(P:a)$ for all $ain h(R)$ with $Ann(a)={0}$. Moreover,<br>
$P$ is a graded $r$-ideal of $R$ if and only if whenever $A, B$ are graded ideals of<br>
$R$ such that $ABsubseteq P$ and $Abigcap r(h(R))neqphi$, then $Bsubseteq P$.<br>
In this article, we introduce the concept of $huz$-rings. A graded ring $R$<br>
is said to be $huz$-ring if every homogeneous element of $R$ is either a zero<br>
divisor or a unit. In fact, we proved that $R$ is a $huz$-ring if and only<br>
if every graded ideal of $R$ is a graded $r$-ideal. Moreover, assuming that<br>
$R$ is a graded domain, we proved that ${0}$ is the only graded $r$-ideal of $R$.</p>
