Cubic surfaces with one rational line over finite fields
Jenny Cooley
Let Fq be a finite field with q=8 or q at least 16. Let S be a smooth cubic surface defined over Fq containing at least one rational line. We use a pigeonhole principle to prove th…

Generators for Cubic Surfaces with two Skew Lines over Finite Fields
Jenny Cooley
Let S be a smooth cubic surface defined over a field K. As observed by Segre and Manin, there is a secant and tangent process on S that generates new K-rational points from old. It…
