CORRECTION TO THE ARTICLE ON THE EMBEDDED ASSOCIATED PRIMES OF MONOMIAL IDEALS
Let I⊂R=K[x1,…,xn] be a monomial ideal, 𝔪=(x1,…,xn), t a positive integer, and y1,…,ys be distinct variables in R such that, for each i=1,…,s, 𝔪∖yi∉Ass(R∕(I∖yi)t), where I∖yi denotes the deletion of I at yi. It is shown in Theorem 3.4 of the article in question that 𝔪∈Ass(R∕It) if and only if 𝔪∈Ass(R∕(It:∏i=1syi)). As an application of Theorem 3.4, it is argued in Theorem 3.6 that under certain conditions, every unmixed König ideal is normally torsion-free. In addition, Theorem 3.7 states that under certain conditions a square-free monomial ideal is normally torsion-free. It turns out that these conditions are not enough to obtain the desired statements in Theorems 3.6 and 3.7. We update these conditions to validate the conclusions of Theorems 3.6 and 3.7. For this purpose, it is enough for us to replace the expression “𝔪∖xi∉Ass(R∕(I∖xi)t)” with the new expression “I∖xi is normally torsion-free”. It should be noted that the previous proofs are still correct.
期刊介绍:
Rocky Mountain Journal of Mathematics publishes both research and expository articles in mathematics, and particularly invites well-written survey articles.
The Rocky Mountain Journal of Mathematics endeavors to publish significant research papers and substantial expository/survey papers in a broad range of theoretical and applied areas of mathematics. For this reason the editorial board is broadly based and submissions are accepted in most areas of mathematics.
In addition, the journal publishes specialized conference proceedings.
