Results of Essan proved that the sets of associated prime ideals of $\sigma(I^n)$, which denoted by $Ass(A/\sigma(I^n))$, stabilize to $A_{\sigma}(I)$. We give some properties of the sets $S^{\sigma}_{n}(I)=Ass(A/\sigma(I^n))\setminus A_{\sigma}(I)$, with $n$ small, which are the sets of $\sigma$-sporadic prime divisors of $I$.We also give some relationships between $\sigma(f_I)$-superficial elements and asymptotic prime $\sigma$-divisors, where $\sigma (f_I)$ is the $\sigma$-closure of the $I$-adic filtration $f_I=(I^n)_{n\in\mathbb{N}}$.}, keywords = {Noetherian ring,Filtration,semi-prime operation,associated prime ideals,superficial elements}, url = {https://jart.guilan.ac.ir/article_2714.html}, eprint = {https://jart.guilan.ac.ir/article_2714_3bb28c732e69e2ea353a223c92597da3.pdf} }
