Complexity, curvature and homological dimension of modules under linkage

Subhadip Bhowmick, Dipankar Ghosh

In this article, we analyze how (projective and injective) complexity, curvature, and complete intersection dimension behave under linkage of modules and ideals. Let $R$ be a Goren…

Asymptotic prime divisors and Vasconcelos invariant

Dipankar Ghosh, Ramakrishna Nanduri, Siddhartha Pramanik

Let $R$ be a Noetherian ring, $I$ an ideal of $R$ , and $M$ a finitely generated $R$ -module. In this article, we prove that $$\mathrm{Ass}_R(M/I^{n} M) = \mathrm{Ass}_R(0:_{M} I) \c…

Coherent functors, powers of ideals, and asymptotic stability

Souvik Dey, Dipankar Ghosh, Siddhartha Pramanik +2

Let $R$ be a Noetherian ring, $I_{1}, \dots, I_{r}$ be ideals of $R$ , and $N \subseteq M$ be finitely generated $R$ -modules. Let $S = \bigoplus_{\underline{n} \in \mathbb{N}^r} S_{\under…

Asymptotic v-numbers of graded (co)homology modules involving powers of an ideal

Dipankar Ghosh, Siddhartha Pramanik

Let $R$ be a Noetherian $N$ -graded ring. Let $L$ , $M$ and $N$ be finitely generated graded $R$ -modules with $N \subseteq M$ . For a homogeneous ideal $I$ , and for each fixe…
