Koszul cohomology of Čech cohomology modules

Maryam Jahangiri

Let $R$ be a commutative Noetherian ring, let $x = x_{1}, \dots, x_{n}$ be an $R$ -regular sequence, and let $y = y_{1}, \dots, y_{m}$ be a sequence of elements of $R$ . Put $I=(…

Bass numbers of graded components of local cohomology modules

Maryam Jahangiri

Let $R=\bigoplus_{n\in \NN_0}R_n$ be a standard graded ring, $R_+=\bigoplus_{n\in \NN}R_n$ its irrelevant ideal, and $M$ a finitely generated graded $R$ -module. In this paper, we s…

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 $…
