On Graded $\phi$-$1$-absorbing prime ideals

Let $G$ be a group, $R$ be a $G$-graded commutative ring with nonzero unity and $GI(R)$ be the set of all graded ideals of $R$. Suppose that $\phi:GI(R)\rightarrow GI(R)\cup\{\emptyset\}$ is a function. In this article, we introduce and study the concept of graded $\phi$-$1$-absorbing prime ideals. A proper graded ideal $I$ of $R$ is called a graded $\phi$% -$1$-absorbing prime ideal of $R$ if whenever $a,b,c$ are homogeneous nonunit elements of $R$ such that $abc\in I-\phi(I)$, then $ab\in I$ or $c\in I$. Several properties of graded $\phi$-$1$-absorbing prime ideals have been examined.
