In this short note we give a new and correct proof of a result of Ferri and Ferri on q^2–caps of AG(3, q), moreover we prove that sets of AG(3, q) of type (1, q,q + 1) with respect to the planes of AG(3, q) have size at most q2 with equality if and only if K is a cap.

Abstract
In this short note we give a new and correct proof of a result of Ferri and Ferri on q^2–caps of AG(3, q), moreover we prove that sets of AG(3, q) of type (1, q,q + 1) with respect to the planes of AG(3, q) have size at most q2 with equality if and only if K is a cap.File in questo prodotto:
