en Graded r-Ideals تخصصي Special پژوهشي Research paper <p>Let \$G\$ be a group with identity \$e\$ and \$R\$ be a commutative \$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 graded \$r\$-ideal if whenever \$a, bin h(R)\$ such that \$abin P\$ and \$Ann(a)={0}\$, then \$bin P\$. We study and investigate the behavior of graded \$r\$-ideals to introduce&nbsp; several results. We introduced several characterizations for graded \$r\$-ideals;&nbsp; we proved that \$P\$ is a graded \$r\$-ideal of \$R\$ if and only if \$aP=aRbigcap P\$<br> &nbsp;for all \$ain h(R)\$ with \$Ann(a)={0}\$. Also, \$P\$ is a graded \$r\$-ideal of \$R\$&nbsp; if and only if \$P=(P:a)\$ for all \$ain h(R)\$ with \$Ann(a)={0}\$. Moreover,<br> &nbsp;\$P\$ is a graded \$r\$-ideal of \$R\$ if and only if whenever \$A, B\$ are graded ideals of &nbsp; \$R\$ such that \$ABsubseteq P\$ and \$Abigcap r(h(R))neqphi\$, then \$Bsubseteq P\$. In this article, we introduce the concept of \$huz\$-rings. A graded ring \$R\$ is said to be \$huz\$-ring if every homogeneous element of \$R\$ is either a zero&nbsp;divisor or a unit. In fact, we proved that \$R\$ is a \$huz\$-ring if and only if every graded ideal of \$R\$ is a graded \$r\$-ideal. Moreover, assuming that \$R\$ is a graded domain, we proved that \${0}\$ is the only graded \$r\$-ideal of \$R\$.</p> Graded prime ideals, Graded r-ideals. 1 8 http://ijmsi.ir/browse.php?a_code=A-10-2277-1&slc_lang=en&sid=1 R.
