Linked sheaves of modules

Farhad Rahmati, Khadijeh Sayyari

We introduce a notion of linkage for sheaves of modules on connected Noetherian schemes, extending classical linkage of modules. Linkage is defined for stable sheaves admitting fin…

Linkage of sheaves of modules

Farhad Rahmati, Khadijeh Sayyari

Inspired by the works in linkage theory of modules, we define the concept of linkage of sheaves of modules as a generalization of linkage of modules. Thus, we expressed it in geome…

Asymptotic behaviour of graded local cohomology modules via linkage

Maryam Jahangiri, Azadeh Nadali, Khadijeh Sayyari

Assume that $R = \oplus_{n \in N_{0}} R_{n}$ is a standard graded algebra over the local ring $(R_{0}, m_{0})$ , $a$ is a homogeneous ideal of $R$ , $M$ is a finite…

Graded local cohomology modules with respect to the linked ideals

Maryam Jahangiri, Azadeh Nadali, Khadijeh Sayyari

Let $R = \oplus_{n \in N_{0}} R_{n}$ be a standard graded ring, $M$ be a finitely generated graded $R$ -module and $R_{+} := \oplus_{n \in N} R_{n}$ denotes the irrelevant ideal of $R$ . In this p…

Attached and Assoiciated Primes Of Local Cohomology Modules Via Linkage

Maryam Jahangiri, Khadijeh Sayyari

Let $R$ be a commutative Noetherian ring and $M$ be a finitely generated $R$ -module. Considering the new concept of linkage of ideals over a module, we study associated prime ideal…

Cohomological dimension with respect to the linked ideals

Maryam Jahangiri, Khadijeh Sayyari

Let $R$ be a commutative Noetherian ring. Using the new concept of linkage of ideals over a module, we show that if $a$ is an ideal of $R$ which is linked by the ideal $…
