Orthogonal arrays from Hermitian varieties
A. Aguglia, L. Giuzzi
An orthogonal array OA(q^{2n-1},q^{2n-2}, q,2) is constructed from the action of a subset of PGL(n+1,q^2) on some non--degenerate Hermitian varieties in PG(n,q^2). It is also shown…

Algebraic curves and Maximal arcs
A. Aguglia, L. Giuzzi, G. Korchmaros
A lower bound on the minimum degree of the plane algebraic curves containing every point in a large point-set of the Desarguesian plane is obtained. The case where $K…

An algorithm for constructing some maximal arcs in $\PG(2,q^2)$
A. Aguglia, L. Giuzzi
In 1974, J. Thas constructed a new class of maximal arcs for the Desarguesian plane of order . The construction relied upon the existence of a regular spread of tangent lines…
