Topics in the arithmetic of del Pezzo and K3 surfaces

Abstract

In this thesis we study the unirationality of del Pezzo surfaces of degree 2 over finite fields, proving that every such surface is unirational.

We explicitly compute the Picard lattice of the members of a 1-dimensional family of K3 surfaces.

We produce an explicit example of a K3 surface having a particular Picard lattice of rank 2.
