Lo studio delle stutture geometriche discrete, prevalentemente di natura combinatoria, riveste una certa importanza nella teoria dei gruppi di permutazioni. In quest’ambito, sono tuttora in corso ricerche, ci è sembrato pertanto utile presentare u

Segre-type theorems related to blocking sets of lines chosen with respect to a conic in PG(2,q) are currently under investigation. A detailed survey on results and methods used in the proofs is given.

This book provides an accessible and self-contained introduction to the theory of algebraic curves over a finite field, a subject that has been of fundamental importance to mathematics for many years and that has essential applications in areas such

Let C be an irreducible plane curve of PG ( 2 , K ) where K is an algebraically closed field of characteristic p ≥ 0 . A point Q ∈ C is an inner Galois point for C if the projection π Q from Q is Galois. Assume that C has two different inner Gal

Multilevel secret sharing schemes are used in cryptography when a responsibility has to be delegated to qualified groups of participants rather than to a single one. In the present paper we propose a mathematical model for such a scheme based on proj

Hermitian functional and differential codes are AG-codes defined on a Hermitian curve. To ensure good performance, the divisors defining such AG-codes have to be carefully chosen, exploiting the rich combinatorial and algebraic properties of the Herm

We present a new method for the study of hemisystems of the Hermitian surface U 3 of PG ( 3 , q 2 ) . The basic idea is to represent generator-sets of U 3 by means of a maximal curve naturally embedded in U 3 so that a sufficient condition for the ex

A unital, that is a 2 - ( q 3 + 1, q + 1, 1) block-design, is embedded in a projective plane π of order q 2 if its points are points of π and its blocks are subsets of lines of π , the point-block incidences being the same as in π . Regarding uni

Let $\mathcal{X}$ be a (projective, geometrically irreducible, nonsingular) algebraic curve of genus $g \ge 2$ defined over an algebraically closed field $\mathbb{K}$ of odd characteristic $p\ge 0$, and let $\rm{Aut}(\mathcal{X})$ be the group of all

In this paper we use the geometry of finite planes to set up a procedure for the construction of one-factorisations of the complete graph. Let π be a projective plane of order n − 1 with n even containing an oval Ω, and regard Ω as the vertex se
