The linear collineation group of a classical unital of PG(2,q^2) contains a subgroup of homologies of order q+1. In this paper we prove that if U is a unital of PG(2,q^2) stabilized by a homology group of order q + 1 and q is a prime number, then U is a classical unital.

Abstract
The linear collineation group of a classical unital of PG(2,q^2) contains a subgroup of homologies of order q+1. In this paper we prove that if U is a unital of PG(2,q^2) stabilized by a homology group of order q + 1 and q is a prime number, then U is a classical unital.File in questo prodotto:
