On the Frobenius closure of parameter ideals when the ring is F-injective on the punctured spectrum

Duong Thi Huong, Pham Hung Quy

Let $(R, m)$ be an excellent generalized Cohen-Macaulay local ring of dimension $d$ that is $F$ -injective on the punctured spectrum. Let $q$ be a standard parameter idea…

Frobenius test exponent for ideals generated by filter regular sequences

Duong Thi Huong, Pham Hung Quy

Let $(R, m)$ be a Noetherian local ring of prime characteristic $p > 0$ , and $t$ an integer such that $H_{m}^{j} (R) / 0_{H_{m}^{j} (R)}^{F}$ has finite length for all $j < t$ .…

Upper bound of multiplicity in prime characteristic

Duong Thi Huong, Pham Hung Quy

Let $(R, m)$ be a local ring of prime characteristic $p$ of dimension $d$ with the embedding dimension $v$ . Suppose the Frobenius test exponent for parameter ideals $F t e (R)$ …
