Ruled cubic surfaces in PG\((4,q)\), Baer subplanes of PG\((2,q^2)\) and Hermitian curves
Any translation plane \(\pi\) of order \(q^2\) with kernel containing \(GF(q)\) can be represented in \(PG(4,q)\). In the case that \(\pi=PG(2,q^2)\), it is shown how unitals are represented, with consequent characterisations of classical unitals (Hermitian curves).
