Dimension of a ring after localization
Example $u = 1 + X$ and $v = 1 + X^2$ we have $u - v = X - X^2 = X(1 -X)$ is unit in $T_S$ since both $X$ and $1-X$ are units in $T_S$. |

Dear Fred, I do not have that paper. Could you please sent it for me. I think I can prove it. |

I only known Countable Prime Avoidance Lemma for complete local ring before. Thanks you very much for the new form. But the ring in my question do not have this assumption. |

Thanks you Fred. But in my question we do not assume that $R/\mathfrak{m}$ is uncountable. |

I know Countable Prime Avoidance Lemma. But I do not know how to apply it for my question. Could you give a detail answer. |
