Let ( A , 𝔪 ) be a Noetherian local ring of dimension d > 0 and I an 𝔪 -primary ideal of A . In this paper, we discuss a sufficient condition, for the Buchsbaumness of the local ring A to be passed onto the associated graded ring of filtration. Let ℐ denote an I -good filtration. We prove that if A is Buchsbaum and the 𝕀 -invariant, 𝕀 ( A ) and 𝕀 ( G ( ℐ ) ) , coincide then the associated graded ring G ( ℐ ) is Buchsbaum. As an application of our result, we indicate an alternative proof of a conjecture, of Corso on certain boundary conditions for Hilbert coefficients.

相关分级过滤环的 Buchsbaumness
让( 一种 , 𝔪 ) 是一个诺特的局部维环d > 0 和一世 一个𝔪 ——基本理想一种 . 在本文中,我们讨论了局部环的 Buchsbaumness 的充分条件一种 被传递到相关的分级过滤环上。让ℐ 表示一个一世 - 良好的过滤。我们证明如果一种 是布克斯鲍姆和𝕀 - 不变的,𝕀 ( 一种 ) 和𝕀 ( G ( ℐ ) ) , 重合则相关的渐变环G ( ℐ ) 是布克斯鲍姆。作为我们结果的应用,我们指出了一个猜想的替代证明,即 Corso 在希尔伯特系数的某些边界条件上的证明。
