On a lower bound of de Rham depth of affine cone of a projective space in characteristic zero

Majid Eghbali

In this paper, we find out a lower bound of the de Rham depth of affine cone of a projective space.

On the equality of de Rham depth and formal grade in characteristic zero

Majid Eghbali

Let $Y \subset P_{k}^{n}$ be a non-singular proper closed subset of projective $n$ -space over a field $k$ of characteristic zero and let $I \subset R = k [x_{0}, \dots, x_{n}]$ be t…

A note on the use of Frobenius map and D-modules in local cohomology

Majid Eghbali

The Frobenius depth denoted by F-depth defined by Hartshorne-Speiser in 1977 and later by Lyubeznik in 2006, in a different way, for rings of positive characteristic. The first aim…

On an endomorphism ring of local cohomology

Majid Eghbali, Peter Schenzel

Let $I$ be an ideal of a local ring $(R, m)$ with $d = dim R .$ For the local cohomology module $H_{I}^{i} (R)$ it is a well-known fact that it vanishes for $i > d$ and is an A…
