Graded-irreducible ideals are irreducible?
Thank you Fred, I have a quick look their proof. They used the fact $I$ is irreducible iff the index of reducible of $I$ is one. So their proof need Noetheian condition. My proof is also true for $\mathbb{Z}$-graded (I fell it works for $\mathbb{N}^n$-graded also). |

I edited my answer more detail (add a Fact). |

Ring of differential operators of a quotient ring
Maybe the question is true when $R = k[x_1, ..., x_n]$ a polynomial ring. Anh it is enough to understand the rings of diffirential operators of finite $k$-algebra. |
