On the resurgence and asymptotic resurgence of homogeneous ideals

AV Jayanthan, A Kumar, V Mukundan - Mathematische Zeitschrift, 2022 - Springer
Let K be a field and R= K [x 1,…, xn]. We obtain an improved upper bound for asymptotic
resurgence of squarefree monomial ideals in R. We study the effect on the resurgence when …

Extreme values of the resurgence for homogeneous ideals in polynomial rings

B Harbourne, J Kettinger, F Zimmitti - Journal of Pure and Applied Algebra, 2022 - Elsevier
We show that two ostensibly different versions of the asymptotic resurgence introduced by E.
Guardo, B. Harbourne and A. Van Tuyl in 2013 are the same. We also show that the …

Integral closures of powers of sums of ideals

A Banerjee, TH Hà - Journal of Algebraic Combinatorics, 2023 - Springer
Let k be a field, let A and B be polynomial rings over k, and let S= A⊗ k B. Let I⊆ A and J⊆ B
be monomial ideals. We establish a binomial expansion for rational powers of I+ J⊆ S in …

Binomial expansion for saturated and symbolic powers of sums of ideals

HT Hà, AV Jayanthan, A Kumar, HD Nguyen - Journal of Algebra, 2023 - Elsevier
There are two different notions for symbolic powers of ideals existing in the literature, one
defined in terms of associated primes, the other in terms of minimal primes. Elaborating on …

[图书][B] Commutative algebra

I Peeva - 2021 - Springer
The origin of the theory of D-modules can be found in the works of Kashiwara [70] and
Bernstein [9, 10]. The motivation behind Bernstein's approach was to give a solution to a …
