On minimal codes arising from projective embeddings of point-line geometries

Ilaria Cardinali, Luca Giuzzi

Let $C (I^c ◯)$ be the linear code arising from a projective system $I^c ◯$ of $PG (V) .$ Consider the point-line geometry $I^ = (P, L)$ and a project…

On the $1$ -cohomology of $SL (n, K)$ on the dual of its adjoint module

Ilaria Cardinali, Luca Giuzzi, Antonio Pasini

Given a field $K$ , for any $n \geq 3$ the first cohomology group $H^{1} (G_{n}, A_{n}^{*})$ of the special linear group $G_{n} = SL (n, K)$ over the dual $A_{n}^{*}$ of its…

The relatively universal cover of the natural embedding of the long root geometry for the group $SL (n + 1, K)$

I. Cardinali, L. Giuzzi, A. Pasini

The long root geometry $A_{n, {1, n}} (K)$ for the special linear group $SL (n + 1, K)$ admits an embedding in the (projective space of) the vector space of t…

Linear codes arising from the point-hyperplane geometry-Part I: the Segre embedding

Ilaria Cardinali, Luca Giuzzi

Let $V$ be a vector space over the finite field $F_{q}$ with $q$ elements and $I^$ be the image of the Segre geometry $PG (V) \otimes PG (V^{*})$ in $\mathrm{PG}…

Line Hermitian Grassmann Codes and their Parameters

Ilaria Cardinali, Luca Giuzzi

In this paper we introduce and study line Hermitian Grassmann codes as those subcodes of the Grassmann codes associated to the $2$ -Grassmannian of a Hermitian polar space defined o…

Linear codes arising from the point-hyperplane geometry -- Part II: the twisted embedding

Ilaria Cardinali, Luca Giuzzi

Let $I^ˉ $ be the point-hyperplane geometry of a projective space $PG (V),$ where $V$ is a $(n + 1)$ -dimensional vector space over a finite field $F_{q}$ of order $q…
